Renames an index. This is used internally to reindex your data without any downtime.

Using this method, you can keep your existing service running while data from the old index imports into the new index. It doesn’t trigger a complete rebuild of the destination index unless it has replicas.

Moving an index is an “expensive” operation, and is rate-limited. If you have more than 100 pending requests, the engine throttles your requests. If you have more than 5,000 pending requests, further requests are ignored.

Analytics

If an index has analytics data, renaming doesn’t erase it but be aware of the consequences:

  • The destination’s analytics keep their original name
  • A new set of analytics is started with the new name.

To access the original analytics in the dashboard’s Analytics menu, first create a new blank index with the original index name.

During a move operation, if your source index doesn’t exist, the operation is ignored. You can still perform a waitTask for this job.

Moving indices between apps

To move an index between apps, use the copyIndex method.

Moving from and to replicas

You can move a source index to a destination index that has replicas. The process replaces the destination index data with the source index data, and copies that source data to its replicas.

You can’t move from a source index that has replicas, as it would break the relationship with its replicas.

Examples

Move index

1

// Rename indexNameSrc to indexNameDest (and overwrite it)
$index = $client->moveIndex('indexNameSrc', 'indexNameDest');

Parameters

indexNameSrc
type: string
Required

Index name of the index to move.

indexNameDest
type: string
Required

Index name of the destination index.

Response

This section shows the JSON response returned by the API. Since each language encapsulates this response inside objects specific to that language and/or implementation, the actual type in your language might differ from what’s written here. You can view the response in the logs (using the getLogs method).

}
updatedAt
string

The date, in Unix timestamp format, when the job to copy the index was created.

taskID
integer

The taskID used with the waitTask method.

You can use either the source or destination index to wait on the resulting taskID. In either case, the wait includes the entire copy process.
