Miroslav Novak updated ARTEMIS-541:
-----------------------------------
Issue Type: New Feature (was: Bug)
> Optimize live/backup replication after failback
> -----------------------------------------------
>
> Key: ARTEMIS-541
> URL: https://issues.apache.org/jira/browse/ARTEMIS-541
> Project: ActiveMQ Artemis
> Issue Type: New Feature
> Components: Broker
> Affects Versions: 1.3.0
> Reporter: Miroslav Novak
>
> Currently if there is master/slave pair configured using replicated journal
> then after each failback when master is starting, it copies the whole journal
> directory from slave.
> This seems to ineffective as master might have significant part of backups
> journal before it failed.
> If only differences between journals would be transfered then it would be
> effective especially in case when failback is completed and master starts to
> synchronize the whole journal back to slave. It copies the whole journal to
> backup again which is almost the same. This would greatly speed up
> synchronization of slave and safe network bandwidth.
