Limitations of Group Replication with Oracle GoldenGate for MySQL

Here are the limitations of support when running group replication with Oracle GoldenGate for MySQL:

  • Oracle GoldenGate Extract with MySQL 21.7 Group Replication does not support multi-primary Group Replication mode.

  • Oracle GoldenGate Extract with MySQL Group Replication does not support writing to remote trails. If using RMTTRAILwith an Extract, the Extract will abend with the following error

    "Trail file ea is remote. Only local trail allowed for this extract."

    In this example, ea is the remote trail file name.

    If you need to use remote trails, then you can use data Pump to send the trail in Classic Architecture. In Microservices Architecture, use the DISTPATH to transport the trail. See Manage Distribution Paths.
