Subject Re: replication - how to change peer cluster key (zookeeper)
Date Thu, 11 Jul 2019 01:45:05 GMT
Hi marjana.  when you alter to the new replication peer, you only want the
new replication data redirect to
the new slave cluster ?  how about the old data in the master cluster ?  is
that necessary to migrate to the
new slave cluster also ?  In our XiaoMi clusters, when doing the migration
to a new slave cluster. we would
like to do the following:

1. add a disabled peer for the new slave cluster (enqueue the newly written
data during the snapshot exporting);
2. create a snapshot in the source cluster;
3. export  snapshot to the new slave cluster;
4. enable the disabled peer for new slave cluster; (replicate all the stuck
log to new slave).
5. remove the original replication peer.

Hope it will be helpful for you.
