stack commented on HBASE-9416:
------------------------------
Thats coolio. So, instead of a set of handlers, we have the disruptor doing
handoff? Was there an issue if the disruptor ring was not big enough and if we
were not servicing it fast enough, it could overwrite outstanding events with
new ones (maybe I imagined this)? Or does it block before it overruns the old
entries?

> Key: HBASE-9416
> URL: https://issues.apache.org/jira/browse/HBASE-9416
> Project: HBase
> Issue Type: Improvement
> Components: regionserver
> Affects Versions: 0.98.0
> Reporter: Nicolas Liochon
> Assignee: Nicolas Liochon
> Attachments: disrupt.patch
>
>
> 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.
