Unfreeze index API

Unfreeze index API

Deprecated in 7.14.

Frozen indices are no longer useful due to recent improvements in heap memory usage.

Unfreezes an index.

Request

POST /<index>/_unfreeze

Prerequisites

  • If the Elasticsearch security features are enabled, you must have the manage index privilege for the target index or index alias.

Description

When a frozen index is unfrozen, the index goes through the normal recovery process and becomes writeable again. See Freeze 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

<index>

(Required, string) Identifier for the index.

Examples

The following example freezes and unfreezes an index:

  1. POST /my-index-000001/_freeze
  2. POST /my-index-000001/_unfreeze
