Resizing a Cloud SQL Instance

Cloud SQL Instances can be resized at any time by changing the Database Type – which defines the amounts of RAM, CPU and local SSD storage allocated to an instance.

Changing Database Type

From the Cloud SQL instance view, click the Resize button from the “Size” details section:

Choose a new type and click Save:

Restarting the instance

Following a successful resize the increased vCPU and local SSD allocations are usable straightaway, but the instance will need to be restarted to pick up the new RAM allocation.

The confirmation dialog gives you the option to Restart Now or to click Cancel if you plan to restart later at a more convenient time.

Depending on how busy the database is, there may be a brief interruption while the underlying database engine service is restarted – so for production databases you may wish to restart later by clicking Restart from the instance view.
