# Cloud SQL Administration API . instances

## Instance Methods

Creates a Cloud SQL instance as a clone of the source instance. The API is not ready for Second Generation instances yet.

Deletes a Cloud SQL instance.

Exports data from a Cloud SQL instance to a Google Cloud Storage bucket as a MySQL dump file.

Failover the instance to its failover replica instance.

Retrieves a resource containing information about a Cloud SQL instance.

Imports data into a Cloud SQL instance from a MySQL dump file in Google Cloud Storage.

Creates a new Cloud SQL instance.

Lists instances under a given project in the alphabetical order of the instance name.

Retrieves the next page of results.

Updates settings of a Cloud SQL instance. Caution: This is not a partial update, so you must include values for all the settings that you want to retain. For partial updates, use patch.. This method supports patch semantics.

Promotes the read replica instance to be a stand-alone Cloud SQL instance.

Deletes all client certificates and generates a new server SSL certificate for the instance. The changes will not take effect until the instance is restarted. Existing instances without a server certificate will need to call this once to set a server certificate.

Restarts a Cloud SQL instance.

Restores a backup of a Cloud SQL instance.

Starts the replication in the read replica instance.

Stops the replication in the read replica instance.

Truncate MySQL general and slow query log tables

Updates settings of a Cloud SQL instance. Caution: This is not a partial update, so you must include values for all the settings that you want to retain. For partial updates, use patch.
