Nicolas Liochon commented on HBASE-9416:
----------------------------------------
I've done it on 0.96. Trunk has another level of indirection because of the
scheduler, but the result would be the same (I would put this into the
SimpleRpcScheduler to match). I could even implement it as a specific scheduler
actually, that would be easy and safe. But I was also aiming at changing the
'Reader' part, and this is more difficult in trunk because of the (justified)
separation added by the scheduler.

> Project: HBase
> Issue Type: Improvement
> Components: regionserver
> Affects Versions: 0.98.0

>
> Nasty & hacky patch on top of the 0.96 to get some feedback on adding this
> third party.
> I ran a test doing "gets" on an empty region.
> With the current implementation, we're spending time in the
> LinkedBlockingQueue#put. I was able to do 150K operations per second.
> Using the disruptor allowed me to go to 190 ops/s, i.e. a little be more than
> a 25% improvement.
> Likely there are other improvements in this class as well.
