> Key: HBASE-11590
> URL: https://issues.apache.org/jira/browse/HBASE-11590
> Project: HBase
> Issue Type: Bug
> Components: Client, Performance
> Affects Versions: 1.0.0, 2.0.0
> Reporter: Nicolas Liochon
> Assignee: Nicolas Liochon
> Priority: Minor
> Attachments: ExecutorServiceTest.java, HBASE-11590.v1.patch,
> LifoThreadPoolExecutorSQP.java, tp.patch, UnitQueueP.java, UnitQueuePU.java
>
>
> The JDK TPE creates all the threads in the pool. As a consequence, we create
> (by default) 256 threads even if we just need a few.
> The attached TPE create threads only if we have something in the queue.
> On a PE test with replica on, it improved the 99 latency percentile by 5%.
> Warning: there are likely some race conditions, but I'm posting it here
> because there is may be an implementation available somewhere we can use, or
> a good reason not to do that. So feedback welcome as usual.
