Aurora MySQL database engine updates 2018-06-04 (version 2.02.2) (Deprecated)

Version: 2.02.2

Aurora MySQL 2.02.2 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.

When creating a new Aurora MySQL DB cluster, you can choose compatibility with either MySQL 5.7 or MySQL 5.6. When restoring a MySQL 5.6-compatible snapshot, you can choose compatibility with either MySQL 5.7 or MySQL 5.6.

You can restore snapshots of Aurora MySQL 1.14*, 1.15*, 1.16*, 1.17*, 2.01*, and 2.02 into Aurora MySQL 2.02.2. You can also perform an in-place upgrade from Aurora MySQL 2.01* or 2.02 to Aurora MySQL 2.02.2.

We don't allow in-place upgrade of Aurora MySQL 1.* clusters into Aurora MySQL 2.02.2 or restore to Aurora MySQL 2.02.2 from an Amazon S3 backup. We plan to remove these restrictions in a later Aurora MySQL 2.* release.

The performance schema is disabled for this release of Aurora MySQL 5.7. Upgrade to Aurora 2.03 for performance schema support.

Note

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

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.

Improvements

Critical fixes:

Comparison with Aurora MySQL 5.6

The following Amazon Aurora MySQL features are supported in Aurora MySQL 5.6, but these features are currently not supported in Aurora MySQL 5.7.

Currently, Aurora MySQL 2.01 does not support features added in Aurora MySQL version 1.16 and later. For information about Aurora MySQL version 1.16, see Aurora MySQL database engine updates 2017-12-11 (version 1.16) (Deprecated).

MySQL 5.7 compatibility

Aurora MySQL 2.02.2 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 2.02.2 does not currently support the following MySQL 5.7 features:

  • Global transaction identifiers (GTIDs). Aurora MySQL supports GTIDs in version 2.04 and higher.

  • Group replication plugin

  • Increased page size

  • InnoDB buffer pool loading at startup

  • InnoDB full-text parser plugin

  • Multisource replication

  • Online buffer pool resizing

  • Password validation plugin

  • Query rewrite plugins

  • Replication filtering

  • The CREATE TABLESPACE SQL statement

  • X Protocol

Refer to the Aurora documentation for the full set of CLI commands and differences between Aurora MySQL 2.x and Aurora MySQL 1.x.

Improvements

  • Fixed an issue where an Aurora Writer can occasionally restart when tracking Aurora Replica progress.

  • Fixed an issue where an Aurora Replica restarts or throws an error when a partitioned table is accessed after running index create or drop statements on the table on the Aurora Writer.

  • Fixed an issue where a table on an Aurora Replica is inaccessible while it is applying the changes caused by running ALTER table ADD/DROP column statements on the Aurora Writer.
