  • 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.

  • 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.
