Method: projects.databases.clone

Creates a new database by cloning an existing one.

The new database must be in the same cloud region or multi-region location as the existing database. This behaves similar toFirestoreAdmin.CreateDatabase except instead of creating a new empty database, a new database is created with the database type, index configuration, and documents from an existing database.

Thelong-running operation can be used to track the progress of the clone, with the Operation'smetadata field type being theCloneDatabaseMetadata. Theresponse type is theDatabase if the clone was successful. The new database is not readable or writeable until the LRO has completed.
