Index lifecycle actions

Allocate

Move shards to nodes with different performance characteristics and reduce the number of replicas.

Delete

Permanently remove the index.

Force merge

Reduce the number of index segments and purge deleted documents. Makes the index read-only.

Freeze

Freeze the index to minimize its memory footprint.

Read only

Block write operations to the index.

Rollover

Remove the index as the write index for the rollover alias and start indexing to a new index.

Set priority

Lower the priority of an index as it moves through the lifecycle to ensure that hot indices are recovered first.

Shrink

Reduce the number of primary shards by shrinking the index into a new index.

Unfollow

Convert a follower index to a regular index. Performed automatically before a rollover or shrink action.

Wait for snapshot

Ensure that a snapshot exists before deleting the index.
