    Hi,

    Bit confused. Are you asking about PXC (master-master replication) or native MySQL Replication? Can you explain the scenario?

    If you are asking for native MySQL Replication than there are 2 ways to exclude a database from the replication.

    1. You can exclude it from master by replicating specific DBs which you want through "binlog-do-db" command
    (But, this is not recommended. Please check below post)

    2. You can exclude it on slave by adding option "replicate-wild-ignore-table=db.%" in my.cnf

      Azigui,

      If you were referring to Percona XtraDB Cluster's replication, then no, it's actually not yet possible to do so. Galera replication doesn't support yet local schemas or tables. The only thing you could do for local tables is to convert them into a different engine like myisam for example (if you don't enable its support in your cluster).

            Hi lefred,

            For your information, you can replicate database in myisam since 5.5.24 version of PXC

            Best regards

              Really ? *joking*

              I know but this needs to be enabled so, currently it's the only way to have local tables in PXC nodes.

              Cheers,
