Subject [jira] [Commented] (CASSANDRA-2606) Expose through JMX the ability to repair only the primary range

Sylvain Lebresne commented on CASSANDRA-2606:
---------------------------------------------

bq. nit: should we call it the "partitioner range" or something else b/s "primary," which
has connotations that we'd prefer to avoid?

Agreed, I was thinking the same thing. Not sure 'partitioner range' is really meaningful but
I agree that it'll avoid confusion. I was also thinking of 'local range' as an alternative,
but it's not really more meaningful, just shorter.

> CASSANDRA-2324 introduces the ability to do a repair only on a given range. This ticket
proposes to add a nodetool repairPrimaryRange to trigger the repair of only the primary range
of a node. This allows to repair a full cluster without any work duplication (or at least
make it much simpler). This also introdude a global_repair command to clustertool to trigger
the primary range repair on each node of the cluster one after another (we could do all in
parallel, but that's probably not nice on the cluster).
