Replication

    Managed Service for MySQL clusters use asynchronous row-based replication. The result of a write request is reflected on the cluster replicas with a delay relative to the master. For more information about row-based replication, see the DBMS documentation.

    Due to limited resources, the b1.nano, b1.micro, b2.nano, and b2.micro class hosts are not replicated.

    Global transaction identifiers (GTID) are used, too. They help maintain the consistency of data across cluster hosts.
