# Clone index
|
|
|
|
The clone index API operation clones all data in an existing read-only index into a new index. The new index cannot already exist.
|
|
|
|
## Example
|
|
|
|
```json
|
|
PUT /sample-index1/_clone/cloned-index1
|
|
{
|
|
"settings": {
|
|
"index": {
|
|
"number_of_shards": 2,
|
|
"number_of_replicas": 1
|
|
}
|
|
},
|
|
"aliases": {
|
|
"sample-alias1": {}
|
|
}
|
|
}
|
|
```
|
|
{% include copy-curl.html %}
|
|
|
|
## Path and HTTP methods
|
|
|
|
```
|
|
POST /<source-index>/_clone/<target-index>
|
|
PUT /<source-index>/_clone/<target-index>
|
|
```
|
|
|
|
## Index naming restrictions
|
|
|
|
OpenSearch indexes have the following naming restrictions:
|
|
|
|
- All letters must be lowercase.
|
|
- Index names can't begin with underscores (`_`) or hyphens (`-`).
|
|
- Index names can't contain spaces, commas, or the following characters:
|
|
|
|
`:`, `"`, `*`, `+`, `/`, `\`, `|`, `?`, `#`, `>`, or `<`
|
|
|
|
## URL parameters
|
|
|
|
Your request must include the source and target indexes. All other clone index parameters are optional.
|
|
|
|
Parameter | Type | Description
|
|
:--- | :--- | :---
|
|
<source-index> | String | The source index to clone.
|
|
<target-index> | String | The index to create and add cloned data to.
|
|
wait_for_active_shards | String | The number of active shards that must be available before OpenSearch processes the request. Default is 1 (only the primary shard). Set to all or a positive integer. Values greater than 1 require replicas. For example, if you specify a value of 3, the index must have two replicas distributed across two additional nodes for the operation to succeed.
|
|
cluster_manager_timeout | Time | How long to wait for a connection to the cluster manager node. Default is `30s`.
|
|
timeout | Time | How long to wait for the request to return. Default is `30s`.
|
|
wait_for_completion | Boolean | When set to `false`, the request returns immediately instead of after the operation is finished. To monitor the operation status, use the [Tasks API]({{site.url}}{{site.baseurl}}/api-reference/tasks/) with the task ID returned by the request. Default is `true`.
|
|
task_execution_timeout | Time | The explicit task execution timeout. Only useful when wait_for_completion is set to `false`. Default is `1h`.
|
|
|
|
## Request body
|
|
|
|
The clone index API operation creates a new target index, so you can specify any [index settings]({{site.url}}{{site.baseurl}}/im-plugin/index-settings/) and [aliases]({{site.url}}{{site.baseurl}}/opensearch/index-alias/) to apply to the target index.
|
|
|
|

{
|
|
"acknowledged": true,
|
|
"shards_acknowledged": true,
|
|
"index": "cloned-index1"
