Unfreeze index API

edit

Unfreeze index API

edit

Deprecated in 7.14.

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

Unfreezes an index.

Request

edit

POST /<index>/_unfreeze

Prerequisites

edit

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

Description

edit

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

edit

<index>: (Required, string) Identifier for the index.

Examples

edit

The following example freezes and unfreezes an index:

POST /my-index-000001/_freeze
POST /my-index-000001/_unfreeze
