Aurora MySQL database engine updates 2023-03-24 (version 2.11.2, compatible with MySQL 5.7.12)

Version: 2.11.2

Aurora MySQL 2.11.2 is generally available. Aurora MySQL 2.11 versions are compatible with MySQL 5.7.12. For more information on community changes, see Changes in MySQL 5.7.12 (2016-04-11, General Availability).

The currently supported Aurora MySQL releases are 2.07.*, 2.11.*, 3.01.*, 3.02.* and 3.03.*.

You can upgrade an existing Aurora MySQL 2.* database cluster to Aurora MySQL 2.11.2. You can also restore a snapshot from any currently supported Aurora MySQL release into Aurora MySQL 2.11.2.

If you upgrade an Aurora MySQL global database to version 2.11.*, you must upgrade your primary and secondary DB clusters to the exact same version, including the patch level. For more information on upgrading the minor version of an Aurora global database, see Minor version upgrades.

Immediately after an in-place engine version upgrade to Aurora MySQL 2.11.* is performed, an operating system upgrade is applied automatically to all affected instances on the db.r4, db.r5, db.t2, and db.t3 DB instance classes, if the instances are running an old operating system version. In a Multi-AZ DB cluster, all of the reader instances apply the operating system upgrade first. When the operating system upgrade on the first reader instance is finished, a failover occurs and the previous writer instance is upgraded.

Note

The operating system upgrade isn't applied automatically to Aurora global databases during major version upgrades.

If you have any questions or concerns, Amazon Support is available on the community forums and through Amazon Support. For more information, see Maintaining an Amazon Aurora DB cluster in the Amazon Aurora User Guide.

Note

For information on how to upgrade your Aurora MySQL database cluster, see Upgrading the minor version or patch level of an Aurora MySQL DB cluster in the Amazon Aurora User Guide.

Improvements

General improvements:

  • Fixed an issue where DB instances using binary log replication may experience an increase in CPU utilization and connection failures when multiple binary log replication consumers are attached.

  • Fixed an issue that can cause a reader instance in a global database secondary Region to become out of sync after upgrading to Aurora MySQL version 2.11 if the primary database writer is on Aurora MySQL version 2.10.

Availability improvements:

  • Fast insert isn't enabled in this Aurora MySQL version, due to an issue that can cause inconsistencies when running queries such as INSERT INTO, SELECT, and FROM. For more information on the fast insert optimization, see Amazon Aurora MySQL performance enhancements.
