Along with this minor version, we’ve added support for Global Transaction Identifiers (GTIDs) and Delayed Replication to MySQL version 8.0. These two features were previously unavailable in Amazon RDS for MySQL version 8.0, and are now available for MySQL version 8.0.26 and higher.
Global transaction identifiers (GTIDs) are unique identifiers generated for committed MySQL transactions. You can use GTID-based replication to make binlog replication simpler and easier to troubleshoot when using Amazon RDS for MySQL read replicas or with an external MySQL database. For more details see Using GTID-based Replication for MySQL in the Amazon RDS User Guide.
Delayed Replication allows you to configure a read replica to lag a fixed time interval behind the source database. You can introduce this intentional delay to help with disaster recovery, such as recovering from a human error that accidentally dropped a database table. For more details on delayed replication see Working with MySQL read replicas in the Amazon RDS user guide.
