Dangling indexes API

Dangling indexes API

Introduced 1.0

After a node joins a cluster, dangling indexes occur if any shards exist in the node’s local directory that do not already exist in the cluster. Dangling indexes can be listed, deleted, or imported.

Path and HTTP methods

List dangling indexes:

GET /_dangling

copy

Import a dangling index:

POST /_dangling/<index-uuid>

copy

Delete a dangling index:

DELETE /_dangling/<index-uuid>

copy

Path parameters

Path parameters are required.

Path parameter	Description
index-uuid	UUID of index.

Query parameters

Query parameters are optional.

Query parameter	Data type	Description
accept_data_loss	Boolean	Must be set to `true` for an `import` or `delete` because OpenSearch is unaware of where the dangling index data came from.
timeout	Time units	The amount of time to wait for a response. If no response is received in the defined time period, an error is returned. Default is `30` seconds.
cluster_manager_timeout	Time units	The amount of time to wait for a connection to the cluster manager. If no response is received in the defined time period, an error is returned. Default is `30` seconds.
