* If the {es} {security-features} are enabled, you must have at least one of the `manage`
|
|
<<privileges-list-indices,index privilege>>, the `manage_data_stream_lifecycle` index privilege, or the
|

==== {api-description-title}
|
|
|
|
Gets the lifecycle of the specified data streams. If multiple data streams are requested but at least one of them
|
|
does not exist, then the API will respond with `404` since at least one of the requested resources could not be retrieved.
|
|
If the requested data streams do not have a lifecycle configured they will still be included in the API response but the
|
|
`lifecycle` key will be missing.

The conditions which will trigger the rollover of a backing index as configured by the cluster setting
