Subject [jira] [Comment Edited] (HBASE-9934) Mesh replication (a.k.a. multi master replication)

----------------------------------------------------------------

That is the first proposal. It will not work where people have a mixed setup. The 2nd one,
where a link (source, sink) pair is specified to be belonging to a mesh network should work
better, but might be more dev work.

Also, when you were cleaning my comment, the diagram got changed. Below is the fixed version.

C4 <\-> C3 <\-> C5 <-> C6
            / \
       C1 - C2

> We can add a new mode in replication to not forward edits from other clusters. Not sure
what should be done when some clusters are configured with this setting and some aren't.
