To set up a new instance with a flexible instance configuration, see our documentation here.

February 24, 2021

Cloud SQL now offers faster maintenance, with average connectivity loss lasting 90 seconds or less on average. See more about maintenance timelines.

Cloud SQL now exposes the metric database/memory/total_usage. This metric provides visibility into the database working set (including buffer cache). You can find this metric in the Metrics explorer within the Monitoring dashboard.

For more information about database/memory/total_usage, see Cloud SQL Metrics.

December 17, 2020

In Cloud SQL for MySQL, parallel replication is generally available for improving replication performance.

November 19, 2020

October 21, 2020

Cloud SQL for MySQL supports binary logging on read replicas for MySQL versions 5.7 and 8.0.

October 12, 2020

Cloud SQL now offers "deny maintenance periods". With deny maintenance periods, you can prevent automatic maintenance from occurring during a specific time period. For example, the end-of-year holiday season is a time of peak load that requires heightened focus on infrastructure stability for many retail businesses. By setting a deny maintenance period from mid-October to mid-January, these businesses can prevent planned upgrades from Cloud SQL during their busiest time of year.

September 24, 2020

MySQL 5.6.42 is upgraded to 5.6.47.

September 21, 2020

Cloud SQL has upgraded Replicating from an external server to version 1.1. You can now:

Replicate from sources where GTID is not enabled.
Allow Cloud SQL to copy data directly from an external server to a Cloud SQL replica.
Use new APIs that give you greater control to verify replication requirements, retry after making external server configuration changes, and remove the 30-minute limit for successful connectivity to an external server.

September 15, 2020

Cloud SQL now offers serverless export. With serverless export, Cloud SQL performs the export from a temporary instance. Offloading the export operation allows databases on the primary instance to continue to serve queries and perform other operations at the usual performance rate.

August 25, 2020

Cloud SQL for MySQL 8.0 is now generally available. If you have not used MySQL 8.0, familiarize yourself with the What is new in MySQL 8.0 and Changes in MySQL 8.0.

To get started using MySQL 8.0 on Cloud SQL, see Creating instances.

June 23, 2020

Committed use discounts (CUDs) are now available to purchase for Cloud SQL. CUDs provide discounted prices in exchange for your commitment to use a minimum level of resources for a specified term. With committed use discounts for Cloud SQL, you can earn a deep discount off your cost of use in exchange for committing to continuously use database instances in a particular region for a 1- or 3-year term. See the documentation for more details.

June 08, 2020

Support for asia-southeast2 region (Jakarta).

May 18, 2020

Cloud SQL now supports read replicas in a different region than that of the primary instance, providing additional protection against regional outages and improving read performance by making replicas available closer to your application. To get started, see Cross-region replicas.

Cloud SQL instances using private IP are now accessible across regions, at the regular cross-region network egress cost.

February 27, 2020

Cloud SQL now supports customer-managed encryption keys (CMEK). With CMEK, you can encrypt Cloud SQL instances using a key you manage. To learn more about CMEK, see the Overview of customer managed encryption keys (CMEK). To start using CMEK, see Using customer-managed encryption keys (CMEK).

October 18, 2019

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.

June 25, 2019

This release increases the maximum data storage for instances of MySQL (MySQL Second Generation) and PostgreSQL. The maximum data storage is increased from 10,230 GB to 30,720 GB. For Cloud SQL storage limits, see Limits. You can limit your automatic storage increases; see Automatic storage increase limit.

May 24, 2019

Cloud SQL now allows you to specify a location for backups, and to restrict data to a single region. To learn about custom backup locations, see Custom backup locations. To learn how to set a custom location for a backup, see Setting and viewing a custom location for backups.
