galera Master-Master cluster with cross sites replication

sklamsklam EntrantCurrent User Role Novice
I am running galera Master-Master cluster in one site with 3 master nodes. its version is 5.5 and it works fine.
Now, I would replicate the data to another site. Its latency is around 20ms and i would not want to extend the existing cluster to the remote site.
Any suggestion?
thanks a lot

    Hi sklam;

    The typical solution would be to setup a slave cluster at the new site and connect it back to your master cluster / site via async replication (standard MySQL replication). That way you will have the copy of your data at the new site for disaster recovery / failover purposes without any performance hit on your master cluster.

    Hi Scott
    Thanks for the suggestion :) . We are trying to deploy this way.

    Besides, just wonder gmcast.segment in Galera 3 could help on this case?

    Thanks again.

    Hi sklam;

    I could not comment on Galera/XtraDB Cluster specifics as I do not use it myself, but hopefully one of the Percona people who know it well can help you out. =)
