For Cloud SQL Enterprise Plus edition instances, advanced disaster recovery (DR) is now generally available (GA). For more information, see Advanced disaster recovery (DR) and Use advanced disaster recovery (DR).

The write endpoint feature is now available in Preview. This endpoint is a global domain name service (DNS) name. This name resolves to the IP address of the current primary Cloud SQL instance that's enabled with private services access.

By using a write endpoint, you can avoid having to make application connection changes after performing a switchover or replica failover operation to test or mitigate a regional failure. For more information, see Configure private IP.

November 18, 2024

October 03, 2024

You can now configure server certificate authority (CA) mode when you create a Cloud SQL instance. With server CA mode, you have two options:

  • Per-instance CA: this is the default configuration. With this option, an internal CA dedicated to each Cloud SQL instance signs the server certificate for that instance.
  • Shared CA: with this option, the Cloud SQL instance uses a CA hierarchy consisting of a root CA and subordinate server CAs managed by Cloud SQL and hosted on Google Cloud Certificate Authority Service (CA Service). The subordinate server CAs in a region sign the server certificates and are shared across instances in the region. This option can be used only with MySQL 8.0.30 and later.

For more information about each option, see Certificate authority (CA) hierarchies. This feature is in Preview.

October 01, 2024

Cloud SQL for MySQL 8.4 is now generally available. For more information about the differences between MySQL 8.4 and MySQL 8.0, review What Is New in MySQL 8.4 since MySQL 8.0.

By default, if you specify MySQL 8.4 as the version when you create a Cloud SQL instance (either primary or replica) using the gcloud CLI or the REST API, then the Cloud SQL edition is Enterprise Plus.

If you specify a version other than MySQL 8.4 or don't specify a version, then the default Cloud SQL edition of the instance is Enterprise.

For more information about the implementation of MySQL 8.4 in Cloud SQL, see the following topics:

To create a MySQL 8.4 instance in Cloud SQL, see Create instances. Before you upgrade to MySQL 8.4, you must first upgrade to MySQL 8.0.37 or later. To perform a major version upgrade, see Upgrade the database major version in-place. To perform a minor version upgrade of Cloud SQL for MySQL 8.0, see Upgrade the database minor version.

September 16, 2024

Cloud SQL is discontinuing support for legacy high availability (HA) instance configuration on January 6, 2025. After this date, you can't create Cloud SQL for MySQL instances with the legacy configuration for high availability. You also can't enable the legacy configuration for high availability on existing instances. Until January 6, 2025, legacy HA instances are still covered by the Cloud SQL SLA. We recommend that you upgrade your existing legacy HA instances to regional persistent disk HA instances as soon as possible and create new HA instances using regional persistent disk instead.

Starting on May 1, 2025, Cloud SQL will migrate any remaining instances that use the legacy HA configuration to the current HA configuration automatically.

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.

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.
