Aurora MySQL database engine updates 2019-05-09 (version 2.04.3) (Deprecated)

Version: 2.04.3

Aurora MySQL 2.04.3 is generally available. Aurora MySQL 2.x versions are compatible with MySQL 5.7 and Aurora MySQL 1.x versions are compatible with MySQL 5.6.

Currently supported Aurora MySQL releases are 1.19.5, 1.19.6, 1.22.*, 1.23.*, 2.04.*, 2.07.*, 2.08.*, 2.09.*, 2.10.*, 3.01.* and 3.02.*.

When creating a new Aurora MySQL DB cluster (including restoring a snapshot), you have the option of choosing compatibility with either MySQL 5.7 or MySQL 5.6. We do not allow in-place upgrade of Aurora MySQL 1.* clusters or restore of Aurora MySQL 1.* clusters from an Amazon S3 backup into Aurora MySQL 2.04.3. We plan to remove these restrictions in a later Aurora MySQL 2.* release.

You can restore snapshots of Aurora MySQL 1.14.*, 1.15.*, 1.16.*, 1.17.*, 1.18.*, 1.19.*, 2.01.*, 2.02.*, 2.03.*, and 2.04.* into Aurora MySQL 2.04.3.

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

Note

This version is currently not available in the AWS GovCloud (US-West) [us-gov-west-1] and China (Ningxia) [cn-northwest-1] AWS Regions. There will be a separate announcement once it is made available.

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

  • Fixed a bug in binlog replication that can cause an issue on Aurora instances configured as binlog worker.

  • Fixed an out-of-memory condition when handling large stored routines.

  • Fixed an error in handling certain kinds of ALTER TABLE commands.

  • Fixed an issue with aborted connections because of an error in network protocol management.

Comparison with Aurora MySQL version 1

The following Amazon Aurora MySQL features are supported in Aurora MySQL Version 1 (compatible with MySQL 5.6), but these features are currently not supported in Aurora MySQL Version 2 (compatible with MySQL 5.7).

MySQL 5.7 compatibility

Aurora MySQL 2.04.3 is wire-compatible with MySQL 5.7 and includes features such as JSON support, spatial indexes, and generated columns. Aurora MySQL uses a native implementation of spatial indexing using z-order curves to deliver >20x better write performance and >10x better read performance than MySQL 5.7 for spatial datasets.

Aurora MySQL 2.04.3 does not currently support the following MySQL 5.7 features:

  • Group replication plugin

  • Increased page size
