Backport of #50920. Part of #48366. Implement an API for listing,
importing and deleting dangling indices.
Co-authored-by: David Turner <david.turner@elastic.co>
Before #57042 the max_buckets test would consistently pass because the
request would consistently fail. In particular, the request would fail on
the data node. After #57042 it only fails on the coordinating node. When
the max_buckets test is run in a mixed version cluster it consistently
fails on *either* the data node or the coordinating node. Except when
the coordinating node is missing #43095. In that case if the one data
node has #57042 and one does not, *and* the one that doesn't gets the
request first, fails it as expected, and then the coordinating node
retries the request on the node with #57042. When that happens the
request fails mysteriously with "partial shard failures" as the error
message but not partial failures reported. This is *exactly* the bug
fixed in #43095.
This updates the test to be skipped in mixed version clusters without
#43095 because they *sometimes* fail the test spuriously. The request
fails in those cases, just like we expect, but with a mysterious error
message.
Closes#57657
We keep a static list of meta-fields: META_FIELDS_BEFORE_7_8
as it was before.
This is done to ensure the backwards compatability with pre 7.8 nodes.
Closes#57831
When you run a `significant_terms` aggregation on a field and it *is*
mapped but there aren't any values for it then the count of the
documents that match the query on that shard still have to be added to
the overall doc count. I broke that in #57361. This fixes that.
Closes#57402
Merges the remaining implementation of `significant_terms` into `terms`
so that we can more easilly make them work properly without
`asMultiBucketAggregator` which *should* save memory and speed them up.
Relates #56487
When the `terms` agg runs against strings and uses global ordinals it
has an optimization when it collects segments that only ever have a
single value for the particular string. This is *very* common. But I
broke it in #57241. This fixes that optimization and adds `debug`
information that you can use to see how often we collect segments of
each type. And adds a test to make sure that I don't break the
optimization again.
We also had a specialiation for when there isn't a filter on the terms
to aggregate. I had removed that specialization in #57241 which resulted
in some slow down as well. This adds it back but in a more clear way.
And, hopefully, a way that is marginally faster when there *is* a
filter.
Closes#57407
This saves some memory when the `histogram` aggregation is not a top
level aggregation by dropping `asMultiBucketAggregator` in favor of
natively implementing multi-bucket storage in the aggregator. For the
most part this just uses the `LongKeyedBucketOrds` that we built the
first time we did this.
Backport of #56878 to 7.x branch.
With this change the following APIs will be able to resolve data streams:
get index, get mappings and ilm explain APIs.

When the `terms` enum operates on non-numeric data it can collect it via
global ordinals. It actually has two separate collection strategies for,
one "dense" and one "remapping". Each of *those* strategies has two
"iteration" strategies that it uses to build buckets, depending on
whether or not we need buckets with `0` docs in them. Previously this
was done with several `null` checks and never really explained. This
change replaces those checks with two `CollectionStrategy` classes which
have good stuff like documentation.
Backporting #56888 to 7.x branch.
Limit the creation of data streams only for namespaces that have a composable template with a data stream definition.
This way we ensure that mappings/settings have been specified and will be used at data stream creation and data stream rollover.
Also remove `timestamp_field` parameter from create data stream request and
let the create data stream api resolve the timestamp field
from the data stream definition snippet inside a composable template.
Relates to #53100
This saves memory when running numeric significant terms which are not
at the top level by merging its collection into numeric terms and relying
on the optimization that we made in #55873.
Fixes for the REST specification specific to 7.x
* remove ignore "cat.thread_pool.json" and add the "" as valid option. #55984 deprecated this field since it these params here have no effect on this specific API
* remove ignore "indices.put_mapping.json" by adding the required / in the path to pass validation.
Changes:
* Adds API reference docs for the delete snapshot repo API.
* Corrects an error in the delete snapshot repo API spec. Comma-separated
repository names are not supported.
* Relocates the existing delete snapshot repo API example docs.
When `date_histogram` is a sub-aggregator it used to allocate a bunch of
objects for every one of it's parent's buckets. This uses the data
structures that we built in #55873 rework the `date_histogram`
aggregator instead of all of the allocation.
Part of #56487
In KeystoreWrapper class we determine if the error to decrypt a
given keystore is caused by a wrong password based on the exception
that the SunJCE implementation of AES is
throwing(AEADBadTagException). Other implementations from other
Security Providers fail with a different exception and as such we
cannot differentiate between a corrupted file and a wrong password
in a foolproof way.
As in other tests such as in
KeyStoreWrapperTests#testDecryptKeyStoreWithWrongPassword
we handle this by matching both possible exception messages.
This is another part of the breakup of the massive BuildPlugin. This PR
moves the code for configuring publications to a separate plugin. Most
of the time these publications are jar files, but this also supports the
zip publication we have for integ tests.
This adds a few things to the `breakdown` of the profiler:
* `histogram` aggregations now contain `total_buckets` which is the
count of buckets that they collected. This could be useful when
debugging a histogram inside of another bucketing agg that is fairly
selective.
* All bucketing aggs that can delay their sub-aggregations will now add
a list of delayed sub-aggregations. This is useful because we
sometimes have fairly involved logic around which sub-aggregations get
delayed and this will save you from having to guess.
* Aggregtations wrapped in the `MultiBucketAggregatorWrapper` can't
accurately add anything to the breakdown. Instead they the wrapper
adds a marker entry `"multi_bucket_aggregator_wrapper": true` so we
can be quickly pick out such aggregations when debugging.
It also fixes a bug where `_count` breakdown entries were contributing
to the overall `time_in_nanos`. They didn't add a large amount of time
so it is unlikely that this caused a big problem, but I was there.
To support the arbitrary breakdown data this reworks the profiler so
that the `breakdown` can contain any data that is supported by
`StreamOutput#writeGenericValue(Object)` and
`XContentBuilder#value(Object)`.
This commit allows the JSON schema's documentation.url property to have a null value.
This can useful for cases where a feature is under development, and does not have
documentation published yet.
This commit also adds a documentation.url for two ml resources.
Backport: #55377
This commit adds the ability to auto create data streams using index templates v2.
Index templates (v2) now have a data_steam field that includes a timestamp field,
if provided and index name matches with that template then a data stream
(plus first backing index) is auto created.
Relates to #53100
This commit removes the `prefer_v2_templates` flag and setting. This was a brief setting that
allowed specifying whether V1 or V2 template should be used when an index is created. It has been
removed in favor of V2 templates always having priority.
Relates to #53101Resolves#56528
This is not a breaking change because this flag was never in a released version.
`auto_date_histogram` was returning the incorrect `interval` because
of a combination of two things:
1. When pipeline aggregations rewrote `auto_date_histogram` we reset the
interval to 1. Oops. Fixed that.
2. *Every* bucket aggregation was rewriting its buckets as though there
was a pipeline aggregation even if there aren't any. This is a bit
silly so we skip that too.
Closes#56116

This adds a new api to simulate matching the given index name against the
index templates in the system.
The syntax for the new API takes the following form:
POST _index_template/_simulate_index/{index_name}
{
"index_patterns": ["logs-*"],
"priority": 15,
"template": {
"settings": {
"number_of_shards": 3
}
...
}
}
Where the body is optional, but we support the entire body used by the
PUT _index_template/{name} api. When the body is specified we'll simulate
matching the given index against a system that'd have the given index
template together with the index templates that exist in the system.
The response, in both cases, will return the matching template's resolved
settings, mappings and aliases, together with a special field that'll print any
overlapping templates and their corresponding index patterns.

This adds a validation to VSParserHelper to ensure that a field or
script or both are specified by the user. This is technically
required today already, but throws an exception much deeper
in the agg framework and has a very unintuitive error for the user
(as well as eating more resources instead of failing early)
A JSON schema was recently introduced for the REST API specification. #54252
This PR introduces a 3rd party validation tool to ensure that the
REST specification conforms to the schema.
The task is applied to the 3 projects that contain REST API specifications.
The plugin wires this task into the precommit commit task, and should be
considered as part of the public API for the build tools for any plugin
developer to contribute their plugin's specification.
An ignore parameter has been introduced for the task to allow specific
file to be ignored from the validation. The ignored files in this PR
will soon get issues logged and a link so they can be fixed.
Closes#54314
This commit adds a new querystring parameter on the following APIs:
- Index
- Update
- Bulk
- Create Index
- Rollover
These APIs now support a `?prefer_v2_templates=true|false` flag. This flag changes the preference
creation to use either V2 index templates or V1 templates. This flag defaults to `false` and will be
changed to `true` for 8.0+ in subsequent work.
Additionally, setting this flag internally sets the `index.prefer_v2_templates` index-level setting.
This setting is used so that actions that automatically create a new index (things like rollover
initiated by ILM) will inherit the preference from the original index. This setting is dynamic so
that a transition from v1 to v2 templates can occur for long-running indices grouped by an alias
performing periodic rollover.
This also adds support for sending this parameter to the High Level Rest Client.

Backport from: #54726
The INCLUDE_DATA_STREAMS indices option controls whether data streams can be resolved in an api for both concrete names and wildcard expressions. If data streams cannot be resolved then a 400 error is returned indicating that data streams cannot be used.
In this pr, the INCLUDE_DATA_STREAMS indices option is enabled in the following APIs: search, msearch, refresh, index (op_type create only) and bulk (index requests with op type create only). In a subsequent later change, we will determine which other APIs need to be able to resolve data streams and enable the INCLUDE_DATA_STREAMS indices option for these APIs.
Whether an api resolve all backing indices of a data stream or the latest index of a data stream (write index) depends on the IndexNameExpressionResolver.Context.isResolveToWriteIndex().
If isResolveToWriteIndex() returns true then data streams resolve to the latest index (for example: index api) and otherwise a data stream resolves to all backing indices of a data stream (for example: search api).

The secure_settings_password was never taken into consideration in
the ReloadSecureSettings API. This commit fixes that and adds
necessary REST layer testing. Doing so, it also:
- Allows TestClusters to have a password protected keystore

- Adds a parameter to the run task so that elastisearch can
be run with a password protected keystore from source.
The usage of local parameter for GetFieldMappingRequest has been removed from the underlying transport action since v2.0.
This PR deprecates the parameter from rest layer. It will be removed in next major version.

This replaces the last bit of validation that pipeline aggregations
performed on the data nodes with explicit checks in a few
`PipelineAggregationBuilders`. We were *already* catching these
validation errors for pipeline aggregations that require that their
parent be squentially ordered. This just adds validation for pipelines
that require *any* parent like `bucket_selector` and `bucket_sort`.
There were some failures on 7.x of field collapse tests,
where total hits count was less then expected.
This adds an additional test to check total hits count
before field collapse queries to understand if the problem
is with field collapsing or with simply that writes have
not been finished yet

* Use V2 index templates during index creation
This commit changes our index creation code to use (and favor!) V2 index templates during index
creation. The creation precedence goes like so, in order of precedence:
- Existing source `IndexMetadata` - for example, when recovering from a peer or a shrink/split/clone
where index templates should not be applied
- A matching V2 index template, if one is found
- When a V2 template is found, all component templates (in the `composed_of` field) are applied
in the order that they appear, with the index template having the 2nd highest precedence (the
create index request always has the top priority when it comes to index settings)
- All matching V1 templates (the old style)
This also adds index template validation when `PUT`-ing a new v2 index template (because this was
required) and ensures that all index and component templates specify *no* top-level mapping type (it
is automatically added when the template is added to the cluster state).
This does not yet implement fine-grained component template merging of mappings, where we favor
merging only a single field's configuration, that will be done in subsequent work.
This also keeps the existing hidden index behavior present for v1 templates, where a hidden index
will match v2 index templates unless they are global (`*`) templates.

This fixes a serialization bug in `auto_date_histogram` that comes up in
a cluster mixed between pre-7.3.0 and post-7.3.0.
Includes #54429 to keep 7.x looking like master for simpler backports.
Closes#54382
Pipeline aggregations like `stats_bucket`, `sum_bucket`, and
`percentiles_bucket` only operate on buckets that have multiple buckets.
This adds support for those aggregations to `geo_distance`, `ip_range`,
`auto_date_histogram`, and `rare_terms`.
This all happened because we used a marker interface to mark compatible
aggs, `MultiBucketAggregationBuilder` and it was fairly easy to forget
to implement the interface.
This replaces the marker interface with an abstract method in
`AggregationBuilder`, `bucketCardinality` which makes you return `NONE`,
`ONE`, or `MANY`. The `bucket` aggregations can check for `MANY`. At
this point `ONE` and `NONE` amount to about the same thing, but I
suspect that'll be a useful distinction when validating bucket sorts.

This commit changes the pre_filter_shard_size default from 128 to unspecified.
This allows to apply heuristics based on the request and the target indices when deciding
whether the can match phase should run or not. When unspecified, this pr runs the can match phase
automatically if one of these conditions is met:
* The request targets more than 128 shards.
* The request contains read-only indices.
* The primary sort of the query targets an indexed field.
Users can opt-out from this behavior by setting the `pre_filter_shard_size` to a static value.
