public static interface DatabaseAdminGrpc.AsyncService

Cloud Spanner Database Admin API The Cloud Spanner Database Admin API can be used to:

• create, drop, and list databases
• update the schema of pre-existing databases
• create, delete and list backups for a database
• restore a database from an existing backup

Methods

copyBackup(CopyBackupRequest request, StreamObserver<Operation> responseObserver)

public default void copyBackup(CopyBackupRequest request, StreamObserver<Operation> responseObserver)

Starts copying a Cloud Spanner Backup. The returned backup long-running operation will have a name of the format projects/<project>/instances/<instance>/backups/<backup>/operations/<operation_id> and can be used to track copying of the backup. The operation is associated with the destination backup. The metadata field type is CopyBackupMetadata. The response field type is Backup, if successful. Cancelling the returned operation will stop the copying and delete the backup. Concurrent CopyBackup requests can run on the same source backup.

Parameters
Name	Description
request	CopyBackupRequest
responseObserver	io.grpc.stub.StreamObserver<Operation>

createBackup(CreateBackupRequest request, StreamObserver<Operation> responseObserver)

public default void createBackup(CreateBackupRequest request, StreamObserver<Operation> responseObserver)

Starts creating a new Cloud Spanner Backup. The returned backup long-running operation will have a name of the format projects/<project>/instances/<instance>/backups/<backup>/operations/<operation_id> and can be used to track creation of the backup. The metadata field type is CreateBackupMetadata. The response field type is Backup, if successful. Cancelling the returned operation will stop the creation and delete the backup. There can be only one pending backup creation per database. Backup creation of different databases can run concurrently.

Parameters
Name	Description
request	CreateBackupRequest
responseObserver	io.grpc.stub.StreamObserver<Operation>

createDatabase(CreateDatabaseRequest request, StreamObserver<Operation> responseObserver)

public default void createDatabase(CreateDatabaseRequest request, StreamObserver<Operation> responseObserver)

Creates a new Cloud Spanner database and starts to prepare it for serving. The returned long-running operation will have a name of the format <database_name>/operations/<operation_id> and can be used to track preparation of the database. The metadata field type is CreateDatabaseMetadata. The response field type is Database, if successful.

The metadata field type is RestoreDatabaseMetadata. The response type is Database, if successful. Cancelling the returned operation will stop the restore and delete the database. There can be only one database being restored into an instance at a time. Once the restore operation completes, a new restore operation can be initiated, without waiting for the optimize operation associated with the first restore to complete.

Parameters
Name	Description
request	RestoreDatabaseRequest
responseObserver	io.grpc.stub.StreamObserver<Operation>

setIamPolicy(SetIamPolicyRequest request, StreamObserver<Policy> responseObserver)

public default void setIamPolicy(SetIamPolicyRequest request, StreamObserver<Policy> responseObserver)

Sets the access control policy on a database or backup resource. Replaces any existing policy. Authorization requires spanner.databases.setIamPolicy permission on resource. For backups, authorization requires spanner.backups.setIamPolicy permission on resource.

Parameters
Name	Description
request	com.google.iam.v1.SetIamPolicyRequest
responseObserver	io.grpc.stub.StreamObserver<com.google.iam.v1.Policy>

testIamPermissions(TestIamPermissionsRequest request, StreamObserver<TestIamPermissionsResponse> responseObserver)

public default void testIamPermissions(TestIamPermissionsRequest request, StreamObserver<TestIamPermissionsResponse> responseObserver)

Returns permissions that the caller has on the specified database or backup resource. Attempting this RPC on a non-existent Cloud Spanner database will result in a NOT_FOUND error if the user has spanner.databases.list permission on the containing Cloud Spanner instance. Otherwise returns an empty set of permissions. Calling this method on a backup that does not exist will result in a NOT_FOUND error if the user has spanner.backups.list permission on the containing instance.

Parameters
Name	Description
request	com.google.iam.v1.TestIamPermissionsRequest
responseObserver	io.grpc.stub.StreamObserver<com.google.iam.v1.TestIamPermissionsResponse>

updateBackup(UpdateBackupRequest request, StreamObserver<Backup> responseObserver)

public default void updateBackup(UpdateBackupRequest request, StreamObserver<Backup> responseObserver)

Updates a pending or completed Backup.

Parameters
Name	Description
request	UpdateBackupRequest
responseObserver	io.grpc.stub.StreamObserver<Backup>

updateDatabase(UpdateDatabaseRequest request, StreamObserver<Operation> responseObserver)

public default void updateDatabase(UpdateDatabaseRequest request, StreamObserver<Operation> responseObserver)

Updates a Cloud Spanner database. The returned long-running operation can be used to track the progress of updating the database. If the named database does not exist, returns NOT_FOUND. While the operation is pending:

• The database's reconciling field is set to true.
• Cancelling the operation is best-effort. If the cancellation succeeds, the operation metadata's cancel_time is set, the updates are reverted, and the operation terminates with a CANCELLED status.
• New UpdateDatabase requests will return a FAILED_PRECONDITION error until the pending operation is done (returns successfully or with error).
• Reading the database via the API continues to give the pre-request values. Upon completion of the returned operation:
• The new values are in effect and readable via the API.
• The database's reconciling field becomes false. The returned long-running operation will have a name of the format projects/<project>/instances/<instance>/databases/<database>/operations/<operation_id> and can be used to track the database modification. The metadata field type is UpdateDatabaseMetadata. The response field type is Database, if successful.

Parameters
Name	Description
request	UpdateDatabaseRequest
responseObserver	io.grpc.stub.StreamObserver<Operation>

updateDatabaseDdl(UpdateDatabaseDdlRequest request, StreamObserver<Operation> responseObserver)

public default void updateDatabaseDdl(UpdateDatabaseDdlRequest request, StreamObserver<Operation> responseObserver)

Updates the schema of a Cloud Spanner database by creating/altering/dropping tables, columns, indexes, etc. The returned long-running operation will have a name of the format <database_name>/operations/<operation_id> and can be used to track execution of the schema change(s). The metadata field type is UpdateDatabaseDdlMetadata. The operation has no response.

Parameters
Name	Description
request	UpdateDatabaseDdlRequest
responseObserver	io.grpc.stub.StreamObserver<Operation>
