Jonathan Ellis commented on CASSANDRA-6455:
-------------------------------------------
Guess this one fell through the cracks. Assigning to [~krummas] for review.
Yuki, can you give us a hash that this applies to, so we don't have to rebase
just yet?
> Improve concurrency of repair process

> Currently, most of the repair tasks (taking snapshots, send/receiving merkle
> tree, compute MT difference, etc) are done on single threaded
> AntiEntropyStage.
> This causes a problem like CASSANDRA-6415 and likely to cause unnecessary
> wait.
> Also, repair is done one CF at the time. I think we can parallelize
> this(concurrency is configurable by a user based on # of CF and load of the
> nodes) for faster processing.
