Improvements

Aurora MySQL version 3.02.1 is generally available and generally compatible with community MySQL 8.0.23.

Security fixes:

Availability improvements:

  • Fixed an issue which can cause connection failure and high latency when multiple MySQL binary log (binlog) replicas are attached to an Aurora writer node or when there are a large number of concurrent long running queries in conjunction with a surge in new connection requests.

  • Fixed an issue that causes a database restart when advanced auditing for CONNECT events are turned on.

  • Fixed an issue that can cause a database restart on Aurora MySQL read replica instances when internal temporary tables exhaust the allocated size in memory and mmap files set as a customer-configured or default value.

  • Fixed an issue that can cause a read replica to repeatedly restart during concurrent DDL operations on stored procedures.

General improvements:

  • Added support for R6i instances.

Additional Information:

  • Aurora MySQL version 3.02.1 does not contain support for major version upgrades directly from Aurora MySQL version 2 (compatible with MySQL 5.7). To perform a major version upgrade to this version, first perform a major version upgrade to Aurora MySQL version 3.02.0, then perform an in-place minor version upgrade to Aurora MySQL version 3.02.1.
