Hi!

I would like to know about following topic regarding MariaDB.

We would like to run DB cluster with HA (high availability). -- E.g. with MaxScale.

My Q:

Does MariaDB support such mechanism which would be similar to pg_rewind? Reference: PostgreSQL supports such a rewind operation.

Or, are there plans to support such regarding MariaDB? 

( If such would be needed / useful. )

Rewind: "A typical scenario is to bring an old primary server back online after failover as a standby that follows the new primary."

Target: robustness/stability of a DB cluster. Avoiding needs to manually fix DB cluster.
