Import dangling index API

Imports a dangling index.

Request

resp = client.dangling_indices.import_dangling_index(
    index_uuid="<index-uuid>",
    accept_data_loss=True,
)
print(resp)

const response = await client.danglingIndices.importDanglingIndex({
  index_uuid: "<index-uuid>",
  accept_data_loss: "true",
});
console.log(response);

POST /_dangling/<index-uuid>?accept_data_loss=true

Prerequisites

If the Elasticsearch security features are enabled, you must have the manage cluster privilege to use this API.

Description

If Elasticsearch encounters index data that is absent from the current cluster state, those indices are considered to be dangling. For example, this can happen if you delete more than cluster.indices.tombstones.size indices while an Elasticsearch node is offline.

Import a single index into the cluster by referencing its UUID. Use the List dangling indices API to locate the UUID of an index.

Path parameters

<index-uuid>: (Required, string) UUID of the index to import, which you can find using the List dangling indices API.

Query parameters

accept_data_loss: (Required, Boolean) This field must be set to true to import a dangling index. Because Elasticsearch cannot know where the dangling index data came from or determine which shard copies are fresh and which are stale, it cannot guarantee that the imported data represents the latest state of the index when it was last in the cluster.
master_timeout: (Optional, time units) Period to wait for the master node. If the master node is not available before the timeout expires, the request fails and returns an error. Defaults to 30s. Can also be set to -1 to indicate that the request should never timeout.
timeout: (Optional, time units) Period to wait for a response from all relevant nodes in the cluster after updating the cluster metadata. If no response is received before the timeout expires, the cluster metadata update still applies but the response will indicate that it was not completely acknowledged. Defaults to 30s. Can also be set to -1 to indicate that the request should never timeout.

Examples

The following example shows how to import a dangling index:

resp = client.dangling_indices.import_dangling_index(
    index_uuid="zmM4e0JtBkeUjiHD-MihPQ",
    accept_data_loss=True,
)
print(resp)

const response = await client.danglingIndices.importDanglingIndex({
  index_uuid: "zmM4e0JtBkeUjiHD-MihPQ",
  accept_data_loss: "true",
});
console.log(response);

POST /_dangling/zmM4e0JtBkeUjiHD-MihPQ?accept_data_loss=true

The API returns following response:

{
  "acknowledged" : true
}
