|
||||
| indices.recovery.max_concurrent_operations | Integer | The number of operations sent in parallel for each recovery. Default is `1`. |
|

|
||||
| logger.org.opensearch.discovery | String | Loggers accept Log4j2’s built-in log levels: `OFF`, `FATAL`, `ERROR`, `WARN`, `INFO`, `DEBUG`, and `TRACE`. Default is `INFO`. |
|
||||
| breaker.model_inference.limit | String | The limit for the trained model circuit breaker. Default is `50%` of the JVM heap. |
|
||||
| breaker.model_inference.overhead | Integer | The constant that all trained model estimations are multiplied by to determine a final estimation. Default is `1`. |
|
||||
| search.max_buckets | Integer | The maximum number of aggregation buckets allowed in a single response. Default is `65536`. |

|
||||
| script.max_compilations_rate | String | The limit for the number of unique dynamic scripts within a defined interval that are allowed to be compiled. Default is 150 every 5 minutes: `150/5m`. |
|
||||
| cluster.default.index.refresh_interval | Time unit | Sets the refresh interval when the `index.refresh_interval` setting is not provided. This setting can be useful when you want to set a default refresh interval across all indexes in a cluster and also support the `searchIdle` setting. You cannot set the interval lower than the `cluster.minimum.index.refresh_interval` setting. |
|
||||
| cluster.minimum.index.refresh_interval | Time unit | Sets the minimum refresh interval and applies it to all indexes in the cluster. The `cluster.default.index.refresh_interval` setting should be higher than this setting's value. If, during index creation, the `index.refresh_interval` setting is lower than the minimum set, index creation fails. |
|
||||
| cluster.remote_store.translog.buffer_interval | Time unit | The default value of the translog buffer interval used when performing periodic translog updates. This setting is only effective when the index setting `index.remote_store.translog.buffer_interval` is not present. |
|
||||
| cluster.routing.allocation.enable | String | Enables or disables allocation for specific kinds of shards: <br /> <br /> `all` – Allows shard allocation for all types of shards. <br /> <br /> `primaries` – Allows shard allocation for primary shards only. <br /> <br /> `new_primaries` – Allows shard allocation for primary shards for new indexes only. <br /> <br /> `none` – No shard allocations are allowed for any indexes. <br /> <br /> Default is `all`. |
|
||||
| cluster.routing.allocation.node_concurrent_incoming_recoveries | Integer | Configures how many concurrent incoming shard recoveries are allowed to happen on a node. Default is `2`. |
|
||||
| cluster.routing.allocation.node_concurrent_outgoing_recoveries | Integer | Configures how many concurrent outgoing shard recoveries are allowed to happen on a node. Default is `2`. |
|
||||
| cluster.routing.allocation.node_concurrent_recoveries | String | Used to set `cluster.routing.allocation.node_concurrent_incoming_recoveries` and `cluster.routing.allocation.node_concurrent_outgoing_recoveries` to the same value. |
|
||||
| cluster.routing.allocation.node_initial_primaries_recoveries | Integer | Sets the number of recoveries for unassigned primaries after a node restart. Default is `4`. |
|
||||
| cluster.routing.allocation.same_shard.host | Boolean | When set to `true`, multiple copies of a shard are prevented from being allocated to distinct nodes on the same host. Default is `false`. |
|
||||
| cluster.routing.rebalance.enable | String | Enables or disables rebalancing for specific kinds of shards: <br /> <br /> `all` – Allows shard balancing for all types of shards. <br /> <br /> `primaries` – Allows shard balancing for primary shards only. <br /> <br /> `replicas` – Allows shard balancing for replica shards only. <br /> <br /> `none` – No shard balancing is allowed for any indexes. <br /> <br /> Default is `all`. |
|
||||
| cluster.routing.allocation.allow_rebalance | String | Specifies when shard rebalancing is allowed: <br /> <br /> `always` – Always allow rebalancing. <br /> <br /> `indices_primaries_active` – Only allow rebalancing when all primaries in the cluster are allocated. <br /> <br /> `indices_all_active` – Only allow rebalancing when all shards in the cluster are allocated. <br /> <br /> Default is `indices_all_active`. |
|
||||
| cluster.routing.allocation.cluster_concurrent_rebalance | Integer | Allows you to control how many concurrent shard rebalances are allowed across a cluster. Default is `2`. |
|
||||
| cluster.routing.allocation.balance.shard | Floating point | Defines the weight factor for the total number of shards allocated per node. Default is `0.45`. |
|
||||
| cluster.routing.allocation.balance.index | Floating point | Defines the weight factor for the number of shards per index allocated on a node. Default is `0.55`. |
|
||||
| cluster.routing.allocation.balance.threshold | Floating point | The minimum optimization value of operations that should be performed. Default is `1.0`. |
|
||||
| cluster.routing.allocation.balance.prefer_primary | Boolean | When set to `true`, OpenSearch attempts to evenly distribute the primary shards between the cluster nodes. Enabling this setting does not always guarantee an equal number of primary shards on each node, especially in the event of failover. Changing this setting to `false` after it was set to `true` does not invoke redistribution of primary shards. Default is `false`.
|
||||
| cluster.routing.allocation.disk.threshold_enabled | Boolean | When set to `false`, disables the disk allocation decider. This will also remove any existing `index.blocks.read_only_allow_delete index blocks` when disabled. Default is `true`. |
|
||||
| cluster.routing.allocation.disk.watermark.low | String | Controls the low watermark for disk usage. When set to a percentage, OpenSearch will not allocate shards to nodes with that percentage of disk used. This can also be entered as ratio value, like `0.85`. Finally, this can also be set to a byte value, like `400mb`. This setting does not affect the primary shards of newly-created indexes, but will prevent their replicas from being allocated. Default is `85%`. |
|
||||
| cluster.routing.allocation.disk.watermark.high | String | Controls the high watermark. OpenSearch will attempt to relocate shards away from a node whose disk usage is above the percentage defined. This can also be entered as a ratio value, like `0.85`. Finally, this can also be set to a byte value, like `400mb`. This setting affects the allocation of all shards. Default is `90%`. |
|
||||
| cluster.routing.allocation.disk.watermark.flood_stage | String | Controls the flood stage watermark. This is a last resort to prevent nodes from running out of disk space. OpenSearch enforces a read-only index block (`index.blocks.read_only_allow_delete`) on every index that has one or more shards allocated on the node, and that has at least one disk exceeding the flood stage. The index block is released once the disk utilization falls below the high watermark. This can also be entered as a ratio value, like `0.85`. Finally, this can also be set to a byte value, like `400mb`. Default is `95%`. |
|
||||
| cluster.info.update.interval | Time unit | Sets how often OpenSearch should check disk usage for each node in the cluster. Default is `30s`. |
|
||||
| cluster.routing.allocation.include.<attribute> | Enum | Allocates shards to a node whose `attribute` has at least one of the included comma-separated values. |
|
||||
| cluster.routing.allocation.require.<attribute> | Enum | Only allocates shards to a node whose `attribute` has all of the included comma-separated values. |
|
||||
| cluster.routing.allocation.exclude.<attribute> | Enum | Does not allocate shards to a node whose `attribute` has any of the included comma-separated values. The cluster allocation settings support the following built-in attributes: <br /> <br /> `_name` – Match nodes by node name. <br /> <br /> `_host_ip` – Match nodes by host IP address. <br /> <br /> `_publish_ip` – Match nodes by publish IP address. <br /> <br /> `_ip` – Match either `_host_ip` or `_publish_ip`. <br /> <br /> `_host` – Match nodes by hostname. <br /> <br /> `_id` – Match nodes by node ID. <br /> <br /> `_tier` – Match nodes by data tier role. |
|
||||
| cluster.routing.allocation.shard_movement_strategy | Enum | Determines the order in which shards are relocated from outgoing to incoming nodes. This setting supports the following strategies: <br /> <br /> `PRIMARY_FIRST` – Primary shards are relocated first, before replica shards. This prioritization may help prevent a cluster's health status from going red if the relocating nodes fail during the process. <br /> <br /> `REPLICA_FIRST` – Replica shards are relocated first, before primary shards. This prioritization may help prevent a cluster's health status from going red when carrying out shard relocation in a mixed-version, segment-replication-enabled OpenSearch cluster. In this situation, primary shards relocated to OpenSearch nodes of a newer version could try to copy segment files to replica shards on an older version of OpenSearch, which would result in shard failure. Relocating replica shards first may help to avoid this in multi-version clusters. <br /> <br /> `NO_PREFERENCE` – The default behavior in which the order of shard relocation has no importance.
|
||||
| cluster.blocks.read_only | Boolean | Sets the entire cluster to read-only. Default is `false`. |
|
||||
| cluster.blocks.read_only_allow_delete | Boolean | Similar to `cluster.blocks.read_only` but allows you to delete indexes. |
|
||||
| cluster.max_shards_per_node | Integer | Limits the total number of primary and replica shards for the cluster. The limit is calculated as follows: `cluster.max_shards_per_node` multiplied by the number of non-frozen data nodes. Shards for closed indexes do not count toward this limit. Default is `1000`. |
|
||||
| cluster.persistent_tasks.allocation.enable | String | Enables or disables allocation for persistent tasks: <br /> <br /> `all` – Allows persistent tasks to be assigned to nodes. <br /> <br /> `none` – No allocations are allowed for persistent tasks. This does not affect persistent tasks already running. <br /> <br /> Default is `all`. |
|
||||
| cluster.persistent_tasks.allocation.recheck_interval | Time unit | The cluster manager automatically checks whether or not persistent tasks need to be assigned when the cluster state changes in a significant way. There are other factors, such as memory usage, that will affect whether or not persistent tasks are assigned to nodes but do not otherwise cause the cluster state to change. This setting defines how often assignment checks are performed in response to these factors. Default is `30 seconds`, with a minimum of `10 seconds` being required. |
|
||||
| remote_store.moving_average_window_size | Integer | The moving average window size used to calculate the rolling statistic values exposed through the [Remote Store Stats API]({{site.url}}{{site.baseurl}}/tuning-your-cluster/availability-and-recovery/remote-store/remote-store-stats-api/). Default is `20`. Minimum enforced is `5`. |
|
||||
| indices.time_series_index.default_index_merge_policy | String | This setting allows you to specify the default merge policy for time-series indexes, particularly for those with an `@timestamp` field, such as data streams. The two available options are `tiered` (default) and `log_byte_size`. We recommend using `log_byte_size` for time-series indexes to enhance the performance of range queries with the `@timestamp` field. To override the merge policy on a per-index basis, you can use the `index.merge.policy` index setting. |

# Index settings
|
||||
|
||||
You can specify index settings at index creation. There are two types of index settings:
|
||||
|
||||
- [Static index settings](#static-index-settings) are settings that you cannot update while the index is open. To update a static setting, you must close the index, update the setting, and then reopen the index.
|
||||
- [Dynamic index settings](#dynamic-index-settings) are settings that you can update at any time.
|
||||
|
||||
## Specifying a setting when creating an index
|
||||
|
||||
When creating an index, you can specify its static or dynamic settings as follows:
|
||||
|
||||
```json
|
||||
PUT /testindex
|
||||
{
|
||||
"settings": {
|
||||
"index.number_of_shards": 1,
|
||||
"index.number_of_replicas": 2
|
||||
}
|
||||
}
|
||||
```
|
||||
{% include copy-curl.html %}
|
||||
|
||||
## Static index settings
|
||||
|
||||
The following table lists all available static index settings.
|
||||
|
||||
Setting | Description
|
||||
:--- | :---
|
||||
index.number_of_shards | The number of primary shards in the index. Default is 1.
|
||||
index.number_of_routing_shards | The number of routing shards used to split an index.
|
||||
index.shard.check_on_startup | Whether the index's shards should be checked for corruption. Available options are `false` (do not check for corruption), `checksum` (check for physical corruption), and `true` (check for both physical and logical corruption). Default is `false`.
|
||||
index.codec | Determines how the index’s stored fields are compressed and stored on disk. This setting impacts the size of the index shards and the performance of the index operations. Valid values are: <br> - `default`<br> - `best_compression`<br> - `zstd` (OpenSearch 2.9 and later)<br> - `zstd_no_dict`(OpenSearch 2.9 and later). <br>For `zstd` and `zstd_no_dict`, you can specify the compression level in the `index.codec.compression_level` setting. For more information, see [Index codec settings]({{site.url}}{{site.baseurl}}/im-plugin/index-codecs/). Optional. Default is `default`.
|
||||
index.codec.compression_level | The compression level setting provides a tradeoff between compression ratio and speed. A higher compression level results in a higher compression ratio (smaller storage size) with a tradeoff in speed (slower compression and decompression speeds lead to greater indexing and search latencies). Can only be specified if `index.codec` is set to `zstd` and `zstd_no_dict` compression levels in OpenSearch 2.9 and later. Valid values are integers in the [1, 6] range. For more information, see [Index codec settings]({{site.url}}{{site.baseurl}}/im-plugin/index-codecs/). Optional. Default is 3.
|
||||
index.routing_partition_size | The number of shards a custom routing value can go to. Routing helps an imbalanced cluster by relocating values to a subset of shards rather than a single shard. To enable routing, set this value to greater than 1 but less than `index.number_of_shards`. Default is 1.
|
||||
index.soft_deletes.retention_lease.period | The maximum amount of time to retain a shard's history of operations. Default is `12h`.
|
||||
index.load_fixed_bitset_filters_eagerly | Whether OpenSearch should preload cached filters. Available options are `true` and `false`. Default is `true`.
|
||||
index.hidden | Whether the index should be hidden. Hidden indexes are not returned as part of queries that have wildcards. Available options are `true` and `false`. Default is `false`.
|
||||
index.merge.policy | This setting controls the merge policy for the Lucene segments. The available options are `tiered` and `log_byte_size`. The default is `tiered`, but for time-series data, such as log events, we recommend that you use the `log_byte_size` merge policy, which can improve query performance when conducting range queries on the `@timestamp` field. We recommend that you not change the merge policy of an existing index. Instead, configure this setting when creating a new index.
|
||||
|
||||
## Updating a static index setting
|
||||
|
||||
You can update a static index setting only on a closed index. The following example demonstrates updating the index codec setting.
|
||||
|
||||
First, close an index:
|
||||
|
||||
```json
|
||||
POST /testindex/_close
|
||||
```
|
||||
{% include copy-curl.html %}
|
||||
|
||||
Then update the settings by sending a request to the `_settings` endpoint:
|
||||
|
||||
```json
|
||||
PUT /testindex/_settings
|
||||
{
|
||||
"index": {
|
||||
"codec": "zstd_no_dict",
|
||||
"codec.compression_level": 3
|
||||
}
|
||||
}
|
||||
```
|
||||
{% include copy-curl.html %}
|
||||
|
||||
Last, reopen the index to enable read and write operations:
|
||||
|
||||
```json
|
||||
POST /testindex/_open
|
||||
```
|
||||
{% include copy-curl.html %}
|
||||
|
||||
For more information about updating settings, including supported query parameters, see [Update settings]({{site.url}}{{site.baseurl}}/api-reference/index-apis/update-settings/).
|
||||
|
||||
## Dynamic index settings
|
||||
|
||||
The following table lists all available dynamic index settings.
|
||||
|
||||
Setting | Description
|
||||
:--- | :---
|
||||
index.number_of_replicas | The number of replica shards each primary shard should have. For example, if you have 4 primary shards and set `index.number_of_replicas` to 3, the index has 12 replica shards. Default is 1.
|
||||
index.auto_expand_replicas | Whether the cluster should automatically add replica shards based on the number of data nodes. Specify a lower bound and upper limit (for example, 0--9) or `all` for the upper limit. For example, if you have 5 data nodes and set `index.auto_expand_replicas` to 0--3, then the cluster does not automatically add another replica shard. However, if you set this value to `0-all` and add 2 more nodes for a total of 7, the cluster will expand to now have 6 replica shards. Default is disabled.
|
||||
index.search.idle.after | The amount of time a shard should wait for a search or get request until it goes idle. Default is `30s`.
|
||||
index.refresh_interval | How often the index should refresh, which publishes its most recent changes and makes them available for searching. Can be set to `-1` to disable refreshing. Default is `1s`.
|
||||
index.max_result_window | The maximum value of `from` + `size` for searches of the index. `from` is the starting index to search from, and `size` is the number of results to return. Default is 10000.
|
||||
index.max_inner_result_window | The maximum value of `from` + `size` that specifies the number of returned nested search hits and most relevant document aggregated during the query. `from` is the starting index to search from, and `size` is the number of top hits to return. Default is 100.
|
||||
index.max_rescore_window | The maximum value of `window_size` for rescore requests to the index. Rescore requests reorder the index's documents and return a new score, which can be more precise. Default is the same as `index.max_inner_result_window` or 10000 by default.
|
||||
index.max_docvalue_fields_search | The maximum number of `docvalue_fields` allowed in a query. Default is 100.
|
||||
index.max_script_fields | The maximum number of `script_fields` allowed in a query. Default is 32.
|
||||
index.max_ngram_diff | The maximum difference between `min_gram` and `max_gram` values for the NGramTokenizer and NGramTokenFilter. Default is 1.
|
||||
index.max_shingle_diff | The maximum difference between `max_shingle_size` and `min_shingle_size` to feed into the `shingle` token filter. Default is 3.
|
||||
index.max_refresh_listeners | The maximum number of refresh listeners each shard is allowed to have.
|
||||
index.analyze.max_token_count | The maximum number of tokens that can be returned from the `_analyze` API operation. Default is 10000.
|
||||
index.highlight.max_analyzed_offset | The number of characters a highlight request can analyze. Default is 1000000.
|
||||
index.max_terms_count | The maximum number of terms a terms query can accept. Default is 65536.
|
||||
index.max_regex_length | The maximum character length of regex that can be in a regexp query. Default is 1000.
|
||||
index.query.default_field | A field or list of fields that OpenSearch uses in queries in case a field isn't specified in the parameters.
|
||||
index.routing.allocation.enable | Specifies options for the index’s shard allocation. Available options are `all` (allow allocation for all shards), `primaries` (allow allocation only for primary shards), `new_primaries` (allow allocation only for new primary shards), and `none` (do not allow allocation). Default is `all`.
|
||||
index.routing.rebalance.enable | Enables shard rebalancing for the index. Available options are `all` (allow rebalancing for all shards), `primaries` (allow rebalancing only for primary shards), `replicas` (allow rebalancing only for replicas), and `none` (do not allow rebalancing). Default is `all`.
|
||||
index.gc_deletes | The amount of time to retain a deleted document's version number. Default is `60s`.
|
||||
index.default_pipeline | The default ingest node pipeline for the index. If the default pipeline is set and the pipeline does not exist, then index requests fail. The pipeline name `_none` specifies that the index does not have an ingest pipeline.
|
||||
index.final_pipeline | The final ingest node pipeline for the index. If the final pipeline is set and the pipeline does not exist, then index requests fail. The pipeline name `_none` specifies that the index does not have an ingest pipeline.
|
||||
|
||||
## Updating a dynamic index setting
|
||||
|
||||
You can update a dynamic index setting at any time through the API. For example, to update the refresh interval, use the following request:
|
||||
|
||||
```json
|
||||
PUT /testindex/_settings
|
||||
{
|
||||
"index": {
|
||||
"refresh_interval": "2s"
|
||||
}
|
||||
}
|

# Circuit breaker settings
|
||||
|
||||
Circuit breakers prevent OpenSearch from causing a Java OutOfMemoryError. The parent circuit breaker specifies the total available amount of memory for all child circuit breakers. The child circuit breakers specify the total available amount of memory for themselves.
|
||||
|
||||
To learn more about static and dynamic settings, see [Configuring OpenSearch]({{site.url}}{{site.baseurl}}/install-and-configure/configuring-opensearch/index/).
|
||||
|
||||
## Parent circuit breaker settings
|
||||
|
||||
OpenSearch supports the following parent circuit breaker settings:
|
||||
|
||||
- `indices.breaker.total.use_real_memory` (Static, Boolean): If `true`, the parent circuit breaker considers the actual memory usage. Otherwise, the parent circuit breaker considers the amount of memory reserved by the child circuit breakers. Default is `false`.
|
||||
|
||||
- `indices.breaker.total.limit` (Dynamic, percentage): Specifies the initial memory limit for the parent circuit breaker. If `indices.breaker.total.use_real_memory` is `true`, defaults to 95% of the JVM heap. If `indices.breaker.total.use_real_memory` is `false`, defaults to 70% of the JVM heap.
|
||||
|
||||
## Field data circuit breaker settings
|
||||
|
||||
The field data circuit breaker limits the heap memory required to load a field into the field data cache. OpenSearch supports the following field data circuit breaker settings:
|
||||
|
||||
- `indices.breaker.fielddata.limit` (Dynamic, percentage): Specifies the memory limit for the field data circuit breaker. Default is 40% of the JVM heap.
|
||||
|
||||
- `indices.breaker.fielddata.overhead` (Dynamic, double): A constant by which the field data estimations are multiplied to determine the final estimation. Default is 1.03.
|
||||
|
||||
## Request circuit breaker settings
|
||||
|
||||
The request circuit breaker limits the memory required to build data structures that are needed for a request (for example, when calculating aggregations). OpenSearch supports the following request circuit breaker settings:
|
||||
|
||||
- `indices.breaker.request.limit` (Dynamic, percentage): Specifies the memory limit for the request circuit breaker. Default is 60% of the JVM heap.
|
||||
|
||||
- `indices.breaker.request.overhead` (Dynamic, double): A constant by which the request estimations are multiplied to determine the final estimation. Default is 1.
|
||||
|
||||
## In-flight request circuit breaker settings
|
||||
|
||||
The in-flight request circuit breaker limits the memory usage for all currently running incoming requests on transport and HTTP level. The memory usage for a request is based on the content length of the request and includes memory needed for the raw request and a structured object representing the request. OpenSearch supports the following in-flight request circuit breaker settings:
|
||||
|
||||
- `network.breaker.inflight_requests.limit` (Dynamic, percentage): Specifies the memory limit for the in-flight request circuit breaker. Default is 100% of JVM heap (thus, the memory usage limit for an in-flight request is determined by the memory limit of the parent circuit breaker).
|
||||
|
||||
- `network.breaker.inflight_requests.overhead` (Dynamic, double): A constant by which the in-flight request estimations are multiplied to determine the final estimation. Default is 2.
|
||||
|
||||
## Script compilation circuit breaker settings
|
||||
|
||||
The script compilation circuit breaker limits the number of inline script compilations within a time interval. OpenSearch supports the following script compilation circuit breaker setting:
|
||||
|
||||
- `script.max_compilations_rate` (Dynamic, rate): The maximum number of unique dynamic scripts compiled within a time interval for a given context. Default is 150 every 5 minutes (`150/5m`).
|
||||
|
||||
## Regular expression circuit breaker settings
|
||||
|
||||
The regular expression circuit breaker enables or disables regular expressions and limits their complexity. OpenSearch supports the following regular expression circuit breaker settings:
|
||||
|
||||
- `script.painless.regex.enabled` (Static, string): Enables regular expressions in Painless scripts.
|
||||
Valid values are:
|
||||
- `limited`: Enables regular expressions and limits their complexity using the `script.painless.regex.limit-factor` setting.
|
||||
- `true`: Enables regular expressions. Turns off the regular expression circuit breaker and does not limit regular expression complexity.
|
||||
- `false`: Disables regular expressions. If a Painless script contains a regular expression, it returns an error.
|
||||
|
||||
Default is `limited`.
|
||||
|
||||
- `script.painless.regex.limit-factor` (Static, integer): Applied only if `script.painless.regex.enabled` is set to `limited`. Limits the number of characters a regular expression in a Painless script. The character limit is calculated by multiplying the number of characters in the script input by `script.painless.regex.limit-factor`. Default is 6 (thus, if the input has 5 characters, the maximum number of characters in a regular expression is 5 · 6 = 30).

# Cluster settings
|
||||
|
||||
The following settings are related to the OpenSearch cluster.
|
||||
|
||||
To learn more about static and dynamic settings, see [Configuring OpenSearch]({{site.url}}{{site.baseurl}}/install-and-configure/configuring-opensearch/index/).
|
||||
|
||||
## Cluster-level routing and allocation settings
|
||||
|
||||
OpenSearch supports the following cluster-level routing and shard allocation settings. All settings in this list are dynamic:
|
||||
|
||||
- `cluster.routing.allocation.enable` (String): Enables or disables allocation for specific kinds of shards.
|
||||
|
||||
Valid values are:
|
||||
- `all` – Allows shard allocation for all types of shards.
|
||||
- `primaries` – Allows shard allocation for primary shards only.
|
||||
- `new_primaries` – Allows shard allocation for primary shards for new indexes only.
|
||||
- `none` – No shard allocations are allowed for any indexes.
|
||||
|
||||
Default is `all`.
|
||||
|
||||
- `cluster.routing.allocation.node_concurrent_incoming_recoveries` (Integer): Configures how many concurrent incoming shard recoveries are allowed to happen on a node. Default is `2`.
|
||||
|
||||
- `cluster.routing.allocation.node_concurrent_outgoing_recoveries` (Integer): Configures how many concurrent outgoing shard recoveries are allowed to happen on a node. Default is `2`.
|
||||
|
||||
- `cluster.routing.allocation.node_concurrent_recoveries` (String): Used to set `cluster.routing.allocation.node_concurrent_incoming_recoveries` and `cluster.routing.allocation.node_concurrent_outgoing_recoveries` to the same value.
|
||||
|
||||
- `cluster.routing.allocation.node_initial_primaries_recoveries` (Integer): Sets the number of recoveries for unassigned primaries after a node restart. Default is `4`.
|
||||
|
||||
- `cluster.routing.allocation.same_shard.host` (Boolean): When set to `true`, multiple copies of a shard are prevented from being allocated to distinct nodes on the same host. Default is `false`.
|
||||
|
||||
- `cluster.routing.rebalance.enable` (String): Enables or disables rebalancing for specific kinds of shards.
|
||||
|
||||
Valid values are:
|
||||
- `all` – Allows shard balancing for all types of shards.
|
||||
- `primaries` – Allows shard balancing for primary shards only.
|
||||
- `replicas` – Allows shard balancing for replica shards only.
|
||||
- `none` – No shard balancing is allowed for any indexes.
|
||||
|
||||
Default is `all`.
|
||||
|
||||
- `cluster.routing.allocation.allow_rebalance` (String): Specifies when shard rebalancing is allowed.
|
||||
|
||||
Valid values are:
|
||||
- `always` – Always allow rebalancing.
|
||||
- `indices_primaries_active` – Only allow rebalancing when all primaries in the cluster are allocated.
|
||||
- `indices_all_active` – Only allow rebalancing when all shards in the cluster are allocated.
|
||||
|
||||
Default is `indices_all_active`.
|
||||
|
||||
- `cluster.routing.allocation.cluster_concurrent_rebalance` (Integer): Allows you to control how many concurrent shard rebalances are allowed across a cluster. Default is `2`.
|
||||
|
||||
- `cluster.routing.allocation.balance.shard` (Floating point): Defines the weight factor for the total number of shards allocated per node. Default is `0.45`.
|
||||
|
||||
- `cluster.routing.allocation.balance.index` (Floating point): Defines the weight factor for the number of shards per index allocated on a node. Default is `0.55`.
|
||||
|
||||
- `cluster.routing.allocation.balance.threshold` (Floating point): The minimum optimization value of operations that should be performed. Default is `1.0`.
|
||||
|
||||
- `cluster.routing.allocation.balance.prefer_primary` (Boolean): When set to `true`, OpenSearch attempts to evenly distribute the primary shards between the cluster nodes. Enabling this setting does not always guarantee an equal number of primary shards on each node, especially in the event of failover. Changing this setting to `false` after it was set to `true` does not invoke redistribution of primary shards. Default is `false`.
|
||||
|
||||
- `cluster.routing.allocation.disk.threshold_enabled` (Boolean): When set to `false`, disables the disk allocation decider. This will also remove any existing `index.blocks.read_only_allow_delete index blocks` when disabled. Default is `true`.
|
||||
|
||||
- `cluster.routing.allocation.disk.watermark.low` (String): Controls the low watermark for disk usage. When set to a percentage, OpenSearch will not allocate shards to nodes with that percentage of disk used. This can also be entered as ratio value, like `0.85`. Finally, this can also be set to a byte value, like `400mb`. This setting does not affect the primary shards of newly created indexes, but will prevent their replicas from being allocated. Default is `85%`.
|
||||
|
||||
- `cluster.routing.allocation.disk.watermark.high` (String): Controls the high watermark. OpenSearch will attempt to relocate shards away from a node whose disk usage is above the percentage defined. This can also be entered as a ratio value, like `0.85`. Finally, this can also be set to a byte value, like `400mb`. This setting affects the allocation of all shards. Default is `90%`.
|
||||
|
||||
- `cluster.routing.allocation.disk.watermark.flood_stage` (String): Controls the flood stage watermark. This is a last resort to prevent nodes from running out of disk space. OpenSearch enforces a read-only index block (`index.blocks.read_only_allow_delete`) on every index that has one or more shards allocated on the node and that has at least one disk exceeding the flood stage. The index block is released once the disk utilization falls below the high watermark. This can also be entered as a ratio value, like `0.85`. Finally, this can also be set to a byte value, like `400mb`. Default is `95%`.
|
||||
|
||||
- `cluster.info.update.interval` (Time unit): Sets how often OpenSearch should check disk usage for each node in the cluster. Default is `30s`.
|
||||
|
||||
- `cluster.routing.allocation.include.<attribute>` (Enum): Allocates shards to a node whose `attribute` has at least one of the included comma-separated values.
|
||||
|
||||
- `cluster.routing.allocation.require.<attribute>` (Enum): Only allocates shards to a node whose `attribute` has all of the included comma-separated values.
|
||||
|
||||
- `cluster.routing.allocation.exclude.<attribute>` (Enum): Does not allocate shards to a node whose `attribute` has any of the included comma-separated values. The cluster allocation settings support the following built-in attributes.
|
||||
|
||||
Valid values are:
|
||||
- `_name` – Match nodes by node name.
|
||||
- `_host_ip` – Match nodes by host IP address.
|
||||
- `_publish_ip` – Match nodes by publish IP address.
|
||||
- `_ip` – Match either `_host_ip` or `_publish_ip`.
|
||||
- `_host` – Match nodes by hostname.
|
||||
- `_id` – Match nodes by node ID.
|
||||
- `_tier` – Match nodes by data tier role.
|
||||
|
||||
- `cluster.routing.allocation.shard_movement_strategy` (Enum): Determines the order in which shards are relocated from outgoing to incoming nodes.
|
||||
|
||||
This setting supports the following strategies:
|
||||
- `PRIMARY_FIRST` – Primary shards are relocated first, before replica shards. This prioritization may help prevent a cluster's health status from going red if the relocating nodes fail during the process.
|
||||
- `REPLICA_FIRST` – Replica shards are relocated first, before primary shards. This prioritization may help prevent a cluster's health status from going red when carrying out shard relocation in a mixed-version, segment-replication-enabled OpenSearch cluster. In this situation, primary shards relocated to OpenSearch nodes of a newer version could try to copy segment files to replica shards on an older version of OpenSearch, which would result in shard failure. Relocating replica shards first may help to avoid this in multi-version clusters.
|
||||
- `NO_PREFERENCE` – The default behavior in which the order of shard relocation has no importance.
|
||||
|
||||
## Cluster-level shard, block, and task settings
|
||||
|
||||
OpenSearch supports the following cluster-level shard, block, and task settings:
|
||||
|
||||
- `cluster.blocks.read_only` (Boolean): Sets the entire cluster to read-only. Default is `false`.
|
||||
|
||||
- `cluster.blocks.read_only_allow_delete` (Boolean): Similar to `cluster.blocks.read_only`, but allows you to delete indexes.
|
||||
|
||||
- `cluster.max_shards_per_node` (Integer): Limits the total number of primary and replica shards for the cluster. The limit is calculated as follows: `cluster.max_shards_per_node` multiplied by the number of non-frozen data nodes. Shards for closed indexes do not count toward this limit. Default is `1000`.
|
||||
|
||||
- `cluster.persistent_tasks.allocation.enable` (String): Enables or disables allocation for persistent tasks.
|
||||
|
||||
Valid values are:
|
||||
- `all` – Allows persistent tasks to be assigned to nodes.
|
||||
- `none` – No allocations are allowed for persistent tasks. This does not affect persistent tasks already running.
|
||||
|
||||
Default is `all`.
|
||||
|
||||
- `cluster.persistent_tasks.allocation.recheck_interval` (Time unit): The cluster manager automatically checks whether persistent tasks need to be assigned when the cluster state changes in a significant way. There are other factors, such as memory usage, that will affect whether persistent tasks are assigned to nodes but do not otherwise cause the cluster state to change. This setting defines how often assignment checks are performed in response to these factors. Default is `30 seconds`, with a minimum of `10 seconds` being required.
|
||||

OpenSearch supports the following system settings:
|
||||
|
||||
- `cluster.name` (Static, string): The cluster name.
|
||||
|
||||
- `node.name` (Static, string): A descriptive name for the node.
|
||||
|
||||
- `node.roles` (Static, list): Defines one or more roles for an OpenSearch node. Valid values are `cluster_manager`, `data`, `ingest`, `search`, `ml`, `remote_cluster_client`, and `coordinating_only`.
|
||||
|
||||
- `path.data` (Static, string): A path to the directory where your data is stored. Separate multiple locations with commas.

# Discovery and gateway settings
|
||||
|
||||
The following are settings related to discovery and local gateway.
|
||||
|
||||
To learn more about static and dynamic settings, see [Configuring OpenSearch]({{site.url}}{{site.baseurl}}/install-and-configure/configuring-opensearch/index/).
|
||||
|
||||
## Discovery settings
|
||||
|
||||
The discovery process is used when a cluster is formed. It consists of discovering nodes and electing a cluster manager node. OpenSearch supports the following discovery settings:
|
||||
|
||||
- `discovery.seed_hosts` (Static, list): The list of hosts that perform discovery when a node is started. The default list of hosts is `["127.0.0.1", "[::1]"]`.
|
||||
|
||||
- `discovery.seed_providers` (Static, list): Specifies the types of seed hosts provider to use for obtaining seed node addresses in order to start the discovery process.
|
||||
|
||||
- `discovery.type` (Static, string): By default, OpenSearch forms a multi-node cluster. Set `discovery.type` to `single-node` to form a single-node cluster.
|
||||
|
||||
- `cluster.initial_cluster_manager_nodes` (Static, list): A list of cluster-manager-eligible nodes used to bootstrap the cluster.
|
||||
|
||||
## Gateway settings
|
||||
|
||||
The local gateway stores cluster state and shard data that is used when a cluster is restarted. OpenSearch supports the following local gateway settings:
|
||||
|
||||
- `gateway.recover_after_nodes` (Static, integer): After a full cluster restart, the number of nodes that must join the cluster before recovery can begin.
|
||||
|
||||
- `gateway.recover_after_data_nodes` (Static, integer): After a full cluster restart, the number of data nodes that must join the cluster before recovery can begin.
|
||||
|
||||
- `gateway.expected_data_nodes` (Static, integer): The number of data nodes expected to exist in the cluster. After the expected number of nodes joins the cluster, recovery of local shards can begin.
|
||||
|
||||
- `gateway.recover_after_time` (Static, time value): The amount of time to wait before starting recovery if the number of data nodes is less than the expected number of data nodes.

# Index settings
|
||||
|
||||
Index settings can be of two types: [cluster-level settings](#cluster-level-index-settings) that affect all indexes in the cluster and [index-level settings](#index-level-index-settings) that affect individual indexes.
|
||||
|
||||
To learn more about static and dynamic settings, see [Configuring OpenSearch]({{site.url}}{{site.baseurl}}/install-and-configure/configuring-opensearch/index/).
|
||||
|
||||
## Cluster-level index settings
|
||||
|
||||
OpenSearch supports the following cluster-level index settings. All settings in this list are dynamic:
|
||||
|
||||
- `action.auto_create_index` (Boolean): Automatically creates an index if the index doesn't already exist. Also applies any index templates that are configured. Default is `true`.
|
||||
|
||||
- `action.destructive_requires_name` (Boolean): When set to `true`, you must specify the index name to delete an index. You cannot delete all indexes or use wildcards. Default is `true`.
|
||||
|
||||
- `cluster.default.index.refresh_interval` (Time unit): Sets the refresh interval when the `index.refresh_interval` setting is not provided. This setting can be useful when you want to set a default refresh interval across all indexes in a cluster and support the `searchIdle` setting. You cannot set the interval lower than the `cluster.minimum.index.refresh_interval` setting.
|
||||
|
||||
- `cluster.minimum.index.refresh_interval` (Time unit): Sets the minimum refresh interval and applies it to all indexes in the cluster. The `cluster.default.index.refresh_interval` setting should be higher than this setting's value. If, during index creation, the `index.refresh_interval` setting is lower than the minimum set, index creation fails.
|
||||
|
||||
- `cluster.indices.close.enable` (Boolean): Enables closing of open indexes in OpenSearch. Default is `true`.
|
||||
|
||||
- `indices.recovery.max_bytes_per_sec` (String): Limits the total inbound and outbound recovery traffic for each node. This applies to peer recoveries and snapshot recoveries. Default is `40mb`. If you set the recovery traffic value to less than or equal to `0mb`, rate limiting will be disabled, which causes recovery data to be transferred at the highest possible rate.
|
||||
|
||||
- `indices.recovery.max_concurrent_file_chunks` (Integer): The number of file chunks sent in parallel for each recovery operation. Default is `2`.
|
||||
|
||||
- `indices.recovery.max_concurrent_operations` (Integer): The number of operations sent in parallel for each recovery. Default is `1`.
|
||||
|
||||
- `indices.recovery.max_concurrent_remote_store_streams` (Integer): The number of streams to the remote repository that can be opened in parallel when recovering a remote store index. Default is `20`.
|
||||
|
||||
- `indices.time_series_index.default_index_merge_policy` (String): This setting allows you to specify the default merge policy for time-series indexes, particularly for those with an `@timestamp` field, such as data streams. The two available options are `tiered` (default) and `log_byte_size`. Using `log_byte_size` for time-series indexes is recommended for enhancing the performance of range queries with the `@timestamp` field. To override the merge policy on a per-index basis, you can use the `index.merge.policy` index setting.
|
||||
|
||||
- `indices.fielddata.cache.size` (String): The maximum size of the field data cache. May be specified as an absolute value (for example, `8GB`) or a percentage of the node heap (for example, `50%`). This value is static so you must specify it in the `opensearch.yml` file. If you don't specify this setting, the maximum size is unlimited. This value should be smaller than the `indices.breaker.fielddata.limit`. For more information, see [Field data circuit breaker]({{site.url}}{{site.baseurl}}/install-and-configure/configuring-opensearch/circuit-breaker/#field-data-circuit-breaker-settings).
|
||||
|
||||
## Index-level index settings
|
||||
|
||||
You can specify index settings at index creation. There are two types of index settings:
|
||||
|
||||
- [Static index-level index settings](#static-index-level-index-settings) are settings that you cannot update while the index is open. To update a static setting, you must close the index, update the setting, and then reopen the index.
|
||||
- [Dynamic index-level index settings](#dynamic-index-level-index-settings) are settings that you can update at any time.
|
||||
|
||||
### Specifying a setting when creating an index
|
||||
|
||||
When creating an index, you can specify its static or dynamic settings as follows:
|
||||
|
||||
```json
|
||||
PUT /testindex
|
||||
{
|
||||
"settings": {
|
||||
"index.number_of_shards": 1,
|
||||
"index.number_of_replicas": 2
|
||||
}
|
||||
}
|
||||
```
|
||||
{% include copy-curl.html %}
|
||||
|
||||
### Static index-level index settings
|
||||
|
||||
OpenSearch supports the following static index-level index settings:
|
||||
|
||||
- `index.number_of_shards` (Integer): The number of primary shards in the index. Default is 1.
|
||||
|
||||
- `index.number_of_routing_shards` (Integer): The number of routing shards used to split an index.
|
||||
|
||||
- `index.shard.check_on_startup` (Boolean): Whether the index's shards should be checked for corruption. Available options are `false` (do not check for corruption), `checksum` (check for physical corruption), and `true` (check for both physical and logical corruption). Default is `false`.
|
||||
|
||||
- `index.codec` (String): Determines how the index’s stored fields are compressed and stored on disk. This setting impacts the size of the index shards and the performance of the index operations.
|
||||
|
||||
Valid values are:
|
||||
|
||||
- `default`
|
||||
- `best_compression`
|
||||
- `zstd` (OpenSearch 2.9 and later)
|
||||
- `zstd_no_dict`(OpenSearch 2.9 and later)
|
||||
|
||||
For `zstd` and `zstd_no_dict`, you can specify the compression level in the `index.codec.compression_level` setting. For more information, see [Index codec settings]({{site.url}}{{site.baseurl}}/im-plugin/index-codecs/). Optional. Default is `default`.
|
||||
|
||||
- `index.codec.compression_level` (Integer): The compression level setting provides a tradeoff between compression ratio and speed. A higher compression level results in a higher compression ratio (smaller storage size) with a tradeoff in speed (slower compression and decompression speeds lead to greater indexing and search latencies). Can only be specified if `index.codec` is set to `zstd` and `zstd_no_dict` compression levels in OpenSearch 2.9 and later. Valid values are integers in the [1, 6] range. For more information, see [Index codec settings]({{site.url}}{{site.baseurl}}/im-plugin/index-codecs/). Optional. Default is 3.
|
||||
|
||||
- `index.routing_partition_size` (Integer): The number of shards a custom routing value can go to. Routing helps an imbalanced cluster by relocating values to a subset of shards rather than a single shard. To enable routing, set this value to greater than 1 but less than `index.number_of_shards`. Default is 1.
|
||||
|
||||
- `index.soft_deletes.retention_lease.period` (Time unit): The maximum amount of time to retain a shard's history of operations. Default is `12h`.
|
||||
|
||||
- `index.load_fixed_bitset_filters_eagerly` (Boolean): Whether OpenSearch should preload cached filters. Available options are `true` and `false`. Default is `true`.
|
||||
|
||||
- `index.hidden` (Boolean): Whether the index should be hidden. Hidden indexes are not returned as part of queries that have wildcards. Available options are `true` and `false`. Default is `false`.
|
||||
|
||||
- `index.merge.policy` (String): This setting controls the merge policy for the Lucene segments. The available options are `tiered` and `log_byte_size`. The default is `tiered`, but for time-series data, such as log events, we recommend that you use the `log_byte_size` merge policy, which can improve query performance when conducting range queries on the `@timestamp` field. We recommend that you not change the merge policy of an existing index. Instead, configure this setting when creating a new index.
|
||||
|
||||
### Updating a static index setting
|
||||
|
||||
You can update a static index setting only on a closed index. The following example demonstrates updating the index codec setting.
|
||||
|
||||
First, close an index:
|
||||
|
||||
```json
|
||||
POST /testindex/_close
|
||||
```
|
||||
{% include copy-curl.html %}
|
||||
|
||||
Then update the settings by sending a request to the `_settings` endpoint:
|
||||
|
||||
```json
|
||||
PUT /testindex/_settings
|
||||
{
|
||||
"index": {
|
||||
"codec": "zstd_no_dict",
|
||||
"codec.compression_level": 3
|
||||
}
|
||||
}
|
||||
```
|
||||
{% include copy-curl.html %}
|
||||
|
||||
Last, reopen the index to enable read and write operations:
|
||||
|
||||
```json
|
||||
POST /testindex/_open
|
||||
```
|
||||
{% include copy-curl.html %}
|
||||
|
||||
For more information about updating settings, including supported query parameters, see [Update settings]({{site.url}}{{site.baseurl}}/api-reference/index-apis/update-settings/).
|
||||
|
||||
### Dynamic index-level index settings
|
||||
|
||||
OpenSearch supports the following dynamic index-level index settings:
|
||||
|
||||
- `index.number_of_replicas` (Integer): The number of replica shards each primary shard should have. For example, if you have 4 primary shards and set `index.number_of_replicas` to 3, the index has 12 replica shards. Default is 1.
|
||||
|
||||
- `index.auto_expand_replicas` (String): Whether the cluster should automatically add replica shards based on the number of data nodes. Specify a lower bound and upper limit (for example, 0--9) or `all` for the upper limit. For example, if you have 5 data nodes and set `index.auto_expand_replicas` to 0--3, then the cluster does not automatically add another replica shard. However, if you set this value to `0-all` and add 2 more nodes for a total of 7, the cluster will expand to now have 6 replica shards. Default is disabled.
|
||||
|
||||
- `index.search.idle.after` (Time unit): The amount of time a shard should wait for a search or get request until it goes idle. Default is `30s`.
|
||||
|
||||
- `index.refresh_interval` (Time unit): How often the index should refresh, which publishes its most recent changes and makes them available for searching. Can be set to `-1` to disable refreshing. Default is `1s`.
|
||||
|
||||
- `index.max_result_window` (Integer): The maximum value of `from` + `size` for searches of the index. `from` is the starting index to search from, and `size` is the number of results to return. Default is 10000.
|
||||
|
||||
- `index.max_inner_result_window` (Integer): The maximum value of `from` + `size` that specifies the number of returned nested search hits and most relevant document aggregated during the query. `from` is the starting index to search from, and `size` is the number of top hits to return. Default is 100.
|
||||
|
||||
- `index.max_rescore_window` (Integer): The maximum value of `window_size` for rescore requests to the index. Rescore requests reorder the index's documents and return a new score, which can be more precise. Default is the same as `index.max_inner_result_window` or 10000 by default.
|
||||
|
||||
- `index.max_docvalue_fields_search` (Integer): The maximum number of `docvalue_fields` allowed in a query. Default is 100.
|
||||
|
||||
- `index.max_script_fields` (Integer): The maximum number of `script_fields` allowed in a query. Default is 32.
|
||||
|
||||
- `index.max_ngram_diff` (Integer): The maximum difference between `min_gram` and `max_gram` values for the `NGramTokenizer` and `NGramTokenFilter`. Default is 1.
|
||||
|
||||
- `index.max_shingle_diff` (Integer): The maximum difference between `max_shingle_size` and `min_shingle_size` to feed into the `shingle` token filter. Default is 3.
|
||||
|
||||
- `index.max_refresh_listeners` (Integer): The maximum number of refresh listeners each shard is allowed to have.
|
||||
|
||||
- `index.analyze.max_token_count` (Integer): The maximum number of tokens that can be returned from the `_analyze` API operation. Default is 10000.
|
||||
|
||||
- `index.highlight.max_analyzed_offset` (Integer): The number of characters a highlight request can analyze. Default is 1000000.
|
||||
|
||||
- `index.max_terms_count` (Integer): The maximum number of terms a terms query can accept. Default is 65536.
|
||||
|
||||
- `index.max_regex_length` (Integer): The maximum character length of regex that can be in a regexp query. Default is 1000.
|
||||
|
||||
- `index.query.default_field` (List): A field or list of fields that OpenSearch uses in queries in case a field isn't specified in the parameters.
|
||||
|
||||
- `index.routing.allocation.enable` (String): Specifies options for the index’s shard allocation. Available options are `all` (allow allocation for all shards), `primaries` (allow allocation only for primary shards), `new_primaries` (allow allocation only for new primary shards), and `none` (do not allow allocation). Default is `all`.
|
||||
|
||||
- `index.routing.rebalance.enable` (String): Enables shard rebalancing for the index. Available options are `all` (allow rebalancing for all shards), `primaries` (allow rebalancing only for primary shards), `replicas` (allow rebalancing only for replicas), and `none` (do not allow rebalancing). Default is `all`.
|
||||
|
||||
- `index.gc_deletes` (Time unit): The amount of time to retain a deleted document's version number. Default is `60s`.
|
||||
|
||||
- `index.default_pipeline` (String): The default ingest node pipeline for the index. If the default pipeline is set and the pipeline does not exist, then index requests fail. The pipeline name `_none` specifies that the index does not have an ingest pipeline.
|
||||
|
||||
- `index.final_pipeline` (String): The final ingest node pipeline for the index. If the final pipeline is set and the pipeline does not exist, then index requests fail. The pipeline name `_none` specifies that the index does not have an ingest pipeline.
|
||||
|
||||
### Updating a dynamic index setting
|
||||
|
||||
You can update a dynamic index setting at any time through the API. For example, to update the refresh interval, use the following request:
|
||||
|
||||
```json
|
||||
PUT /testindex/_settings
|
||||
{
|
||||
"index": {
|
||||
"refresh_interval": "2s"
|
||||
}
|
||||
}
|
||||
```
|
||||
{% include copy-curl.html %}

# Configuring OpenSearch
|
||||
|
||||
Most OpenSearch configuration can take place in the cluster settings API. Certain operations require you to modify `opensearch.yml` and restart the cluster.
|
||||
There are two types of OpenSearch settings: [dynamic](#dynamic-settings) and [static](#static-settings).
|
||||
|
||||
Whenever possible, use the cluster settings API instead; `opensearch.yml` is local to each node, whereas the API applies the setting to all nodes in the cluster. Certain settings, however, require `opensearch.yml`. In general, these settings relate to networking, cluster formation, and the local file system. To learn more, see [Cluster formation]({{site.url}}{{site.baseurl}}/opensearch/cluster/).
|
||||
## Dynamic settings

## Static settings
|
||||
|
||||
Certain operations are static and require you to modify the `opensearch.yml` [configuration file](#configuration-file) and restart the cluster. In general, these settings relate to networking, cluster formation, and the local file system. To learn more, see [Cluster formation]({{site.url}}{{site.baseurl}}/opensearch/cluster/).
|
||||
|
||||
## Specifying settings as environment variables
|
||||
|
||||
You can specify environment variables as arguments using `-E` when launching OpenSearch:
|
||||
|
||||
```bash
|
||||
./opensearch -Ecluster.name=opensearch-cluster -Enode.name=opensearch-node1 -Ehttp.host=0.0.0.0 -Ediscovery.type=single-node

### (Optional) CORS header configuration
|
||||
If you are working on a client application running against an OpenSearch cluster on a different domain, you can configure headers in `opensearch.yml` to allow for developing a local application on the same machine. Use [Cross Origin Resource Sharing](https://developer.mozilla.org/en-US/docs/Web/HTTP/CORS) so your application can make calls to the OpenSearch API running locally. Add the following lines in your `custom-opensearch.yml` file (note that the "-" must be the first character in each line).

# Network settings
|
||||
|
||||
OpenSearch uses HTTP settings to configure communication with external clients through the REST API and transport settings for internal node-to-node communication within OpenSearch.
|
||||
|
||||
To learn more about static and dynamic settings, see [Configuring OpenSearch]({{site.url}}{{site.baseurl}}/install-and-configure/configuring-opensearch/index/).
|
||||
|
||||
OpenSearch supports the following common network settings:
|
||||
|
||||
- `network.host` (Static, list): Binds an OpenSearch node to an address. Use `0.0.0.0` to include all available network interfaces, or specify an IP address assigned to a specific interface. The `network.host` setting is a combination of `network.bind_host` and `network.publish_host` if they are the same value. An alternative to `network.host` is to configure `network.bind_host` and `network.publish_host` separately as needed. See [Advanced network settings](#advanced-network-settings).
|
||||
|
||||
- `http.port` (Static, single value or range): Binds an OpenSearch node to a custom port or a range of ports for HTTP communication. You can specify an address or a range of addresses. Default is `9200-9300`.
|
||||
|
||||
- `transport.port` (Static, single value or range): Binds an OpenSearch node to a custom port for communication between nodes. You can specify an address or a range of addresses. Default is `9300-9400`.
|
||||
|
||||
## Advanced network settings
|
||||
|
||||
OpenSearch supports the following advanced network settings:
|
||||
|
||||
- `network.bind_host` (Static, list): Binds an OpenSearch node to an address or addresses for incoming connections. Default is the value in `network.host`.
|
||||
|
||||
- `network.publish_host` (Static, list): Specifies an address or addresses that an OpenSearch node publishes to other nodes in the cluster so that they can connect to it.
|

||||
## Advanced HTTP settings
|
||||
|
||||
OpenSearch supports the following advanced network settings for HTTP communication:

An alternative to `http.host` is to configure `http.bind_host` and `http.publish_host` separately as needed.
|
||||
|
||||
- `http.bind_host` (Static, list): Specifies an address or addresses to which an OpenSearch node binds to listen for incoming HTTP connections.
|
||||
|
||||
- `http.publish_host` (Static, list): Specifies an address or addresses that an OpenSearch node publishes to other nodes for HTTP communication.

# Search settings
|
||||
|
||||
OpenSearch supports the following search settings:
|
||||
|
||||
- `search.max_buckets` (Dynamic, integer): The maximum number of aggregation buckets allowed in a single response. Default is `65535`.
|
||||
|
||||
- `search.phase_took_enabled` (Dynamic, Boolean): Enables returning phase-level `took` time values in search responses. Default is `false`.
|
||||
|
||||
- `search.allow_expensive_queries` (Dynamic, Boolean): Allows or disallows expensive queries. For more information, see [Expensive queries]({{site.url}}{{site.baseurl}}/query-dsl/index/#expensive-queries).
|
||||
|
||||
- `search.default_allow_partial_results` (Dynamic, Boolean): A cluster-level setting that allows returning partial search results if a request times out or a shard fails. If a search request contains an `allow_partial_search_results` parameter, the parameter takes precedence over this setting. Default is `true`.
|
||||
|
||||
- `search.cancel_after_time_interval` (Dynamic, time unit): A cluster-level setting that specifies the maximum amount of time that a search request can run before it is canceled at the shard level. After this time has been reached, a request is stopped and all associated tasks are canceled. Default is `-1`.
|
||||
|
||||
- `search.default_search_timeout` (Dynamic, time unit): A cluster-level setting that sets the default timeout for all search requests at the coordinating node level. If the `timeout` is specified in the search request, it takes precedence over this setting. Default is `-1` (no timeout).
|
||||
|
||||
- `search.default_keep_alive` (Dynamic, time unit): Specifies the default keep alive value for scroll and Point in Time (PIT) searches. Because a request may land on a shard multiple times (for example, during the query and fetch phases), OpenSearch opens a _request context_ that exists for the full duration of the request to ensure consistency of the shard state for each individual shard request. In a standard search, once the fetch phase completes, the request context is closed. For a scroll or a PIT search, OpenSearch keeps the request context open until explicitly closed (or until the keep alive time is reached). A background thread periodically checks all open scroll and PIT contexts and deletes the ones that have exceeded their keep alive timeout. The `search.keep_alive_interval` setting specifies how frequently the contexts are checked for expiration. The `search.default_keep_alive` setting is the default deadline for expiration. A scroll or PIT request can explicitly specify the keep alive, which takes precedence over this setting. Default is `5m`.
|
||||
|
||||
- `search.keep_alive_interval` (Static, time unit): Determines the interval at which OpenSearch checks for request contexts that have exceeded their keep alive limit. Default is `1m`.
|
||||
|
||||
- `search.max_keep_alive` (Dynamic, time unit): Specifies the maximum keep alive value. The `max_keep_alive` setting is used as a safety check against the other `keep_alive` settings (for example, `default_keep_alive`) and request-level keep alive settings (for scroll and PIT contexts). If a request exceeds the `max_keep_alive` value in either case, the operation will fail. Default is `24h`.
|
||||
|
||||
- `search.low_level_cancellation` (Dynamic, Boolean): Enables low-level request cancellation. Lucene's classic timeout mechanism only checks the time while collecting search results. However, an expensive query, such as wildcard or prefix, can take a long time to expand before starting to collect results. In this case, the query can run for a period of time that is greater than the timeout value. The low-level cancellation mechanism addresses this scenario by timing out not only while collecting search results but also during the query expansion phase or before performing any Lucene operation. Default is `true`.
|
||||
|
||||
- `search.max_open_scroll_context` (Dynamic, integer): A node-level setting that specifies the maximum number of open scroll contexts for the node. Default is `500`.
|
||||
|
||||
- `search.request_stats_enabled` (Dynamic, Boolean): Turns on node-level collection of phase-timing statistics from the perspective of the coordinator node. The request-level statistics keep track of how long (in total) search requests spend in each of the different search phases. You can retrieve these counters using the [Nodes Stats API]({{site.url}}{{site.baseurl}}/api-reference/nodes-apis/nodes-stats/). Default is `false`.
|
||||
|
||||
- `search.highlight.term_vector_multi_value` (Static, Boolean): Specifies to highlight snippets across values of a multi-valued field. Default is `true`.
|
||||
|
||||

||||

# Security settings
|
||||
|
||||
The Security plugin provides a number of YAML configuration files that are used to store the necessary settings that define the way the Security plugin manages users, roles, and activity within the cluster. For a full list of the Security plugin configuration files, see [Modifying the YAML files]({{site.url}}{{site.baseurl}}/security/configuration/yaml/).
|
||||
|
||||
The following sections describe security-related settings in `opensearch.yml`. To learn more about static and dynamic settings, see [Configuring OpenSearch]({{site.url}}{{site.baseurl}}/install-and-configure/configuring-opensearch/index/).
|
||||
|
||||
## Common settings
|
||||
|
||||
The Security plugin supports the following common settings:
|
||||
|
||||
- `plugins.security.nodes_dn` (Static): Specifies a list of distinguished names (DNs) that denote the other nodes in the cluster. This setting supports wildcards and regular expressions. The list of DNs are also read from the security index **in addition** to the YAML configuration when `plugins.security.nodes_dn_dynamic_config_enabled` is `true`.
|
||||
|
||||
- `plugins.security.nodes_dn_dynamic_config_enabled` (Static): Relevant for `cross_cluster` use cases where there is a need to manage the allow listed `nodes_dn` without having to restart the nodes every time a new `cross_cluster` remote is configured.
|
||||
Setting `nodes_dn_dynamic_config_enabled` to `true` enables **super-admin callable** Distinguished Names APIs, which provide means to update or retrieve `nodes_dn` dynamically. This setting only has effect if `plugins.security.cert.intercluster_request_evaluator_class` is not set. Default is `false`.
|
||||
|
||||
- `plugins.security.authcz.admin_dn` (Static): Defines the DNs of certificates to which admin privileges should be assigned. Required.
|
||||
|
||||
- `plugins.security.roles_mapping_resolution` (Static): Defines how backend roles are mapped to Security roles.
|
||||
|
||||
Valid values are:
|
||||
- `MAPPING_ONLY`(Default): Mappings must be configured explicitly in `roles_mapping.yml`.
|
||||
- `BACKENDROLES_ONLY`: Backend roles are mapped to security roles directly. Settings in `roles_mapping.yml` have no effect.
|
||||
- `BOTH`: Backend roles are mapped to security roles both directly and through `roles_mapping.yml`.
|
||||
|
||||
- `plugins.security.dls.mode` (Static): Sets the document-level security (DLS) evaluation mode. Default is `adaptive`. See [How to set the DLS evaluation mode]({{site.url}}{{site.baseurl}}/security/access-control/document-level-security/#how-to-set-the-dls-evaluation-mode-in-opensearchyml).
|
||||
|
||||
- `plugins.security.compliance.salt` (Static): The salt to use when generating the hash value for field masking. Must be at least 32 characters. Only ASCII characters are allowed. Optional.
|
||||
|
||||
- `config.dynamic.http.anonymous_auth_enabled` (Static): Enables anonymous authentication. This will cause all HTTP authenticators to not challenge. Default is `false`.
|
||||
|
||||
## REST management API settings
|
||||
|
||||
The Security plugin supports the following REST management API settings:
|
||||
|
||||
- `plugins.security.restapi.roles_enabled` (Static): Enables role-based access to the REST management API for listed roles. Roles are separated by a comma. Default is an empty list (no role is allowed to access the REST management API). See [Access control for the API]({{site.url}}{{site.baseurl}}/security/access-control/api/#access-control-for-the-api).
|
||||
|
||||
- `plugins.security.restapi.endpoints_disabled.<role>.<endpoint>` (Static): Disables specific endpoints and their HTTP methods for roles. Values for this setting compose an array of HTTP methods. For example: `plugins.security.restapi.endpoints_disabled.all_access.ACTIONGROUPS: ["PUT","POST","DELETE"]`. By default, all endpoints and methods are allowed. Existing endpoints include `ACTIONGROUPS`, `CACHE`, `CONFIG`, `ROLES`, `ROLESMAPPING`, `INTERNALUSERS`, `SYSTEMINFO`, `PERMISSIONSINFO`, and `LICENSE`. See [Access control for the API]({{site.url}}{{site.baseurl}}/security/access-control/api/#access-control-for-the-api).
|
||||
|
||||
- `plugins.security.restapi.password_validation_regex` (Static): Specifies a regular expression to set the criteria for the login password. For more information, see [Password settings]({{site.url}}{{site.baseurl}}/security/configuration/yaml/#password-settings).
|
||||
|
||||
- `plugins.security.restapi.password_validation_error_message` (Static): Specifies an error message that loads when a password doesn’t pass validation. This setting is used in conjunction with `plugins.security.restapi.password_validation_regex`.
|
||||
|
||||
- `plugins.security.restapi.password_min_length` (Static): Sets the minimum number of characters for the password length when using the score-based password strength estimator. The default is 8. This is also the minimum. For more information, see [Password settings]({{site.url}}{{site.baseurl}}/security/configuration/yaml/#password-settings).
|
||||
|
||||
- `plugins.security.restapi.password_score_based_validation_strength` (Static): Sets a threshold to determine whether the password is strong or weak. Valid values are `fair`, `good`, `strong`, and `very_strong`. This setting is used in conjunction with `plugins.security.restapi.password_min_length`.
|
||||
|
||||
- `plugins.security.unsupported.restapi.allow_securityconfig_modification` (Static): Enables the use of the PUT and PATCH methods for the configuration APIs.
|
||||
|
||||
## Advanced settings
|
||||
|
||||
The Security plugin supports the following advanced settings:
|
||||
|
||||
- `plugins.security.authcz.impersonation_dn` (Static): Enables transport layer impersonation. This allows DNs to impersonate as other users. See [User impersonation]({{site.url}}{{site.baseurl}}/security/access-control/impersonation/).
|
||||
|
||||
- `plugins.security.authcz.rest_impersonation_user` (Static): Enables REST layer impersonation. This allows users to impersonate as other users. See [User impersonation]({{site.url}}{{site.baseurl}}/security/access-control/impersonation/).
|
||||
|
||||
- `plugins.security.allow_default_init_securityindex` (Static): When set to `true`, OpenSearch Security will automatically initialize the configuration index with the files in the `/config` directory if the index does not exist.
|
||||
|
||||
This will use well-known default passwords. Use only in a private network/environment.
|
||||
{: .warning}
|
||||
|
||||
- `plugins.security.allow_unsafe_democertificates` (Static): When set to `true`, OpenSearch starts up with demo certificates. These certificates are issued only for demo purposes.
|
||||
|
||||
These certificates are well known and therefore unsafe for production. Use only in a private network/environment.
|
||||
{: .warning}
|
||||
|
||||
- `plugins.security.system_indices.permission.enabled` (Static): Enables the system index permissions feature. When set to `true`, the feature is enabled and users with permission to modify roles can create roles that include permissions that grant access to system indexes. When set to `false`, the permission is disabled and only admins with an admin certificate can make changes to system indexes. By default, the permission is set to `false` in a new cluster.
|
||||
|
||||
## Expert-level settings
|
||||
|
||||
An expert-level setting should only be configured and deployed by an admin who understands the feature completely. Misunderstandings of a feature can lead to security risks, cause the Security plugin to not operate properly, or cause data loss.
|
||||
{: .warning}
|
||||
|
||||
The Security plugin supports the following expert-level settings:
|
||||
|
||||
- `plugins.security.config_index_name` (Static): The name of the index where `.opendistro_security` stores its configuration.
|
||||
|
||||
- `plugins.security.cert.oid` (Static): Defines the Object Identifier (OID) of server node certificates.
|
||||
|
||||
- `plugins.security.cert.intercluster_request_evaluator_class` (Static): Specifies the implementation of `org.opensearch.security.transport.InterClusterRequestEvaluator` that is used to evaluate intercluster requests. Instances of `org.opensearch.security.transport.InterClusterRequestEvaluator` must implement a single-argument constructor that takes an `org.opensearch.common.settings.Settings` object.
|
||||
|
||||
- `plugins.security.enable_snapshot_restore_privilege` (Static): When set to `false`, this setting disables snapshot restore for regular users. In this case, only snapshot restore requests signed by an admin TLS certificate are accepted. When set to `true` (default), regular users can restore snapshots if they have the `cluster:admin/snapshot/restore`, `indices:admin/create`, and `indices:data/write/index` privileges.
|
||||
|
||||
A snapshot can only be restored when it does not contain global state and does not restore the `.opendistro_security` index.
|
||||
{: .note}
|
||||
|
||||
- `plugins.security.check_snapshot_restore_write_privileges` (Static): When set to `false`, additional index checks are omitted. When set to the default of `true`, attempts to restore snapshots are evaluated for `indices:admin/create` and `"indices:data/write/index`.
|
||||
|
||||
- `plugins.security.cache.ttl_minutes` (Static): Determines how long it takes for authentication caching to time out. The authentication cache helps speed up authentication by temporarily storing user objects returned from the backend so that the Security plugin is not required to make repeated requests for them. Set the value in minutes. The default is `60`. Disable caching by setting the value to `0`.
|
||||
|
||||
- `plugins.security.disabled` (Static): Disables OpenSearch Security.
|
||||
|
||||
Disabling this plugin can expose your configuration (including passwords) to the public.
|
||||
{:warning}
|
||||
|
||||
- `plugins.security.protected_indices.enabled` (Static): If set to `true`, enables protected indexes. Protected indexes are even more secure than regular indexes. These indexes require a role to access like any other traditional index and require an additional role to be visible. This setting is used in conjunction with the `plugins.security.protected_indices.roles` and `plugins.security.protected_indices.indices` settings.
|
||||
|
||||
- `plugins.security.protected_indices.roles` (Static): Specifies a list of roles to which a user must be mapped to access protected indexes.
|
||||
|
||||
- `plugins.security.protected_indices.indices` (Static): Specifies a list of indexes to mark as protected. These indexes will only be visible to users mapped to the roles specified in `plugins.security.protected_indices.roles`. After this requirement is fulfilled, a user will still need to be mapped to the traditional role used to grant access permission to the index.
|
||||
|
||||
- `plugins.security.system_indices.enabled` (Static): If set to `true`, enables system indexes. System indexes are similar to the security index, except that the contents are not encrypted. Indexes configured as system indexes can be accessed by either a super-admin or a user with a role that includes the [system index permission]({{site.url}}{{site.baseurl}}/security/access-control/permissions/#system-index-permissions). For more information about system indexes, see [System indexes]({{site.url}}{{site.baseurl}}/security/configuration/system-indices/).
|
||||
|
||||
- `plugins.security.system_indices.indices` (Static): A list of indexes to be used as system indexes. This setting is controlled by the `plugins.security.system_indices.enabled` setting.
|
||||
|
||||
- `plugins.security.allow_default_init_securityindex` (Static): When set to `true`, sets the Security plugin to its default security settings if an attempt to create the security index fails when OpenSearch launches. Default security settings are stored in YAML files contained in the `opensearch-project/security/config` directory. Default is `false`.
|
||||
|
||||
- `plugins.security.cert.intercluster_request_evaluator_class` (Static): A class to be used for evaluating intercluster communication.
|
||||
|
||||
- `plugins.security.enable_snapshot_restore_privilege` (Static): Enables granting the snapshot restore privilege. Optional. Default is `true`.
|
||||
|
||||
- `plugins.security.check_snapshot_restore_write_privileges` (Static): Enforces write privilege evaluation when creating snapshots. Default is `true`.
|
||||
|
||||
## Audit log settings
|
||||
|
||||
The Security plugin supports the following audit log settings:
|
||||
|
||||
- `plugins.security.audit.enable_rest` (Dynamic): Enables or disables REST request logging. Default is `true` (enable).
|
||||
|
||||
- `plugins.security.audit.enable_transport` (Dynamic): Enables or disables transport-level request logging. Default is `false` (disable).
|
||||
|
||||
- `plugins.security.audit.resolve_bulk_requests` (Dynamic): Enable or disable bulk request logging. When enabled, all subrequests in bulk requests are also logged. Default is `false` (disabled).
|
||||
|
||||
- `plugins.security.audit.config.disabled_categories` (Dynamic): Disables the specified event categories.
|
||||
|
||||
- `plugins.security.audit.ignore_requests` (Dynamic): Excludes the specified requests from being logged. Allows wildcards and regular expressions containing actions or REST request paths.
|
||||
|
||||
- `plugins.security.audit.threadpool.size` (Static): Determines the number of threads in the thread pool used to log events. Default is `10`. Setting this value to `0` disables the thread pool, which means the plugin logs events synchronously.
|
||||
|
||||
- `plugins.security.audit.threadpool.max_queue_len` (Static): Sets the maximum queue length per thread. Default is `100000`.
|
||||
|
||||
- `plugins.security.audit.ignore_users` (Dynamic): An array of users. Audit requests from the users in the list will not be logged.
|
||||
|
||||
- `plugins.security.audit.type` (Static): The destination of audit log events. Valid values are `internal_opensearch`, `external_opensearch`, `debug`, and `webhook`.
|
||||
|
||||
- `plugins.security.audit.config.http_endpoints` (Static): A list of endpoints for `localhost`.
|
||||
|
||||
- `plugins.security.audit.config.index` (Static): The audit log index. The default is `auditlog6`. The index can be static or an index that includes a date so that it rotates on a daily basis, for example, `"'auditlog6-'YYYY.MM.dd"`. In either case, make sure to secure the index properly.
|
||||
|
||||
- `plugins.security.audit.config.type` (Static): Specify the audit log type as `auditlog`.
|
||||
|
||||
- `plugins.security.audit.config.username` (Static): Username for the audit log configuration.
|
||||
|
||||
- `plugins.security.audit.config.password` (Static): Password for the audit log configuration.
|
||||
|
||||
- `plugins.security.audit.config.enable_ssl` (Static): Enables or disables SSL for audit logging.
|
||||
|
||||
- `plugins.security.audit.config.verify_hostnames` (Static): Enables or disables verification of the hostname for SSL/TLS certificates. Default is `true` (enabled).
|
||||
|
||||
- `plugins.security.audit.config.enable_ssl_client_auth` (Static): Enables or disables SSL/TLS client authentication. Default is `false` (disabled).
|
||||
|
||||
- `plugins.security.audit.config.cert_alias` (Static): An alias to the certificate used for audit log access.
|
||||
|
||||
- `plugins.security.audit.config.pemkey_filepath` (Static): The `/config` relative file path to the Privacy Enhanced Mail (PEM) key used for audit logging.
|
||||
|
||||
- `plugins.security.audit.config.pemkey_content` (Static): The base64-encoded content of the PEM key used for audit logging. This is an alternative to `...config.pemkey_filepath`.
|
||||
|
||||
- `plugins.security.audit.config.pemkey_password` (Static): Password for the PEM-formatted private key used by the client.
|
||||
|
||||
- `plugins.security.audit.config.pemcert_filepath` (Static): The `/config` relative file path to the PEM certificate used for audit logging.
|
||||
|
||||
- `plugins.security.audit.config.pemcert_content` (Static): The base64-encoded content of the PEM certificate used for audit logging. This is an alternative to specifying the file path with `...config.pemcert_filepath`.
|
||||
|
||||
- `plugins.security.audit.config.pemtrustedcas_filepath` (Static): The `/config` relative filepath to trusted root certificate authority.
|
||||

The logic used by your job should be defined by a class extended from `ScheduledJobRunner` in the `SampleJobParameter.java` sample file, such as `SampleJobRunner`. While the job is running, there is a locking mechanism you can use to prevent other nodes from running the same job. First, [acquire](https://github.com/opensearch-project/job-scheduler/blob/main/sample-extension-plugin/src/main/java/org/opensearch/jobscheduler/sampleextension/SampleJobRunner.java#L96) the lock. Then make sure to release the lock before the [job finishes](https://github.com/opensearch-project/job-scheduler/blob/main/sample-extension-plugin/src/main/java/org/opensearch/jobscheduler/sampleextension/SampleJobRunner.java#L116).

## Job Scheduler cluster settings
|
||||

The Job Scheduler plugin supports the following cluster settings. All settings are dynamic. To learn more about static and dynamic settings, see [Configuring OpenSearch]({{site.url}}{{site.baseurl}}/install-and-configure/configuring-opensearch/index/).
|
||||
|
||||
| Setting | Data type | Description |
|
||||
:--- | :--- | :---
|
||||
| `plugins.jobscheduler.jitter_limit` | Double | Defines the maximum delay multiplier for job execution time. Too many jobs starting at the same time can cause high resource consumption. To balance the load, you can add a random jitter delay to the start time. For example, if the time interval is 10 minutes and the jitter is 0.6, the next job run will be randomly delayed by a time period between 0 and 6 minutes. |
|
||||
| `plugins.jobscheduler.request_timeout` | Time unit | The background sweep search timeout. Background sweep refers to the automatic scheduling and execution of registered jobs. It occurs on an interval and iterates through each extending plugin's registered job index, searching for jobs to be executed. |
|
||||
| `plugins.jobscheduler.retry_count` | Integer | Used to define the retry count of an exponential backoff policy. Backoff policies determine how long bulk processors will wait before the bulk operation is retried. It is used whenever bulk indexing requests are impacted or rejected because of resource constraints at the time of a request. For the Job Scheduler plugin, this impacts searching registered job indexes. |
|
||||
| `plugins.jobscheduler.sweeper.backoff_millis` | Time unit | Used to define the initial wait period of an exponential backoff policy, in milliseconds. Backoff policies determine how long bulk processors will wait before the bulk operation is retried. It is used whenever bulk indexing requests are impacted or rejected because of resource constraints at the time of a request. For the Job Scheduler plugin, this impacts searching registered job indexes. |
|
||||
| `plugins.jobscheduler.sweeper.page_size` | Integer | Configures the search request used to find job documents within a registered job index. Defines the number of search hits to return. |
|
||||
| `plugins.jobscheduler.sweeper.period` | Time unit | Defines the initial delay period before a background sweep is executed. |

The `plugins.security.allow_default_init_securityindex` setting, when set to `true`, sets the Security plugin to its default security settings if an attempt to create the security index fails when OpenSearch launches. Default security settings are stored in YAML files contained in the `opensearch-project/security/config` directory. By default, this setting is `false`.

One such feature is OpenSearch Dashboards multi-tenancy. Tenants are work spaces that include visualizations, index patterns, and other Dashboards objects. Multi-tenancy allows for the sharing of tenants among users of Dashboards and leverages OpenSearch roles to manage access to tenants and safely make them available to others.
