Dangling indexes API
Introduced 0.1.0
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
Import a dangling index:
POST /_dangling/<index-uuid>
Delete a dangling index:
DELETE /_dangling/<index-uuid>
Path parameters
Path parameters are required.
| Path parameter | Description |

Query parameters
Query parameters are optional.

| accept_data_loss | Boolean | Must be set to true for an import or delete because Lucenia is unaware of where the dangling index data came from. |
