Are There Any Restrictions After GTID Is Enabled for a MySQL DB Instance?
By default, GTID is enabled on RDS for MySQL and cannot be disabled because functions such as the primary/standby relationship establishment depend on GTID. If GTID is disabled, all RDS functions (such as backup and restoration and primary/standby switchover or failover) will be affected or even become unavailable.
After GTID is enabled for MySQL community edition, an error will be reported in the following conditions:
- Create tables (create table...select).
- A transaction is processed by the engine (InnoDB) that supports transactions and the engine (MyISAM) that does not support transactions at the same time.
- Create temporary tables (create temporary table).
RDS for MySQL resolved these issues by optimizing the kernel. You can refer to Upgrading the Minor Version to upgrade the minor version.
