# Dangling indexes API
|
|
|
|
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
|
|
:--- | :---
|
|
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.
