Cloud SQL Second Generation MySQL instances have a new high availability (HA) configuration. The new HA configuration, based on Google's Regional Disks, eliminates replication lag and, combined with automatic failover, provides isolation from many types of infrastructure, hardware, and software failures. Regional disks also ensure that all previously committed database transactions are persisted and available after failover, right up to the time of the failure.

The new high availability configuration is the default. You can continue to use the API to create instances with the legacy high availability configuration (using failover replicas) until the upgrade of existing instances occurs in early 2020. To learn how high availability now works for Second Generation MySQL instances, see the Overview of the high availability configuration. To enable high availability on existing instances, or to create new instances with high availability, see Enabling and disabling high availability on an instance.
