Freeze index API

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.
