Aurora MySQL database engine updates 2019-03-25 (version 2.04.0)

Version: 2.04

Aurora MySQL 2.04 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 (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 2.04.0. We plan to remove these restrictions in a later Aurora MySQL 2.* release.

You can restore snapshots of Aurora MySQL 1.19.*, 2.01.*, 2.02.*, and 2.03.* into Aurora MySQL 2.04.0. You cannot restore snapshots of Aurora MySQL 1.14.* or lower, 1.15.*, 1.16.*, 1.17.*, 1.18.* into Aurora MySQL 2.04.0. This restriction is removed in Aurora MySQL 2.04.1.

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

Note

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

Note

The procedure to upgrade your DB cluster has changed. For more information, see Upgrading the minor version or patch level of an Aurora MySQL DB cluster.

Improvements

  • Fixed an issue where an Aurora Replica incorrectly throws aRunning in read-only mode error when a statement deleting or updating rows in a temporary table contains an InnoDB subquery.

Integration of MySQL bug fixes

  • Bug #26225783: MYSQL CRASH ON CREATE TABLE (REPRODUCEABLE) -> INNODB: ALONG SEMAPHORE WAIT.

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

This Aurora MySQL version 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.

This Aurora MySQL version does not currently support the following MySQL 5.7 features:

  • 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
