Freeze index API

Freezes an index.


POST /<index>/_freeze


A frozen index has almost no overhead on the cluster (except for maintaining its metadata in memory), and is blocked for write operations. See Frozen indices and Unfreeze index.

Freezing an index will close the index and reopen it within the same API call. This causes primaries to not be allocated for a short amount of time and causes the cluster to go red until the primaries are allocated again. This limitation might be removed in the future.

Path parameters

(Required, string) Identifier for the index.


The following example freezes and unfreezes an index:

POST /my_index/_freeze
POST /my_index/_unfreeze
