Freezes an index.
Request
POST /<index>/_freeze
Description
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.
Path Parameters
-
index(required) - (string) Identifier for the index
Examples
The following example freezes and unfreezes an index:
POST /my_index/_freeze POST /my_index/_unfreeze
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.
