> On this [PR|https://github.com/apache/hbase/pull/2909] [~stack] rightly pointed out that the thread pool just spins up threads that remain idle for 99.999% of time. Java's [ThreadPoolExecutor|https://docs.oracle.com/en/java/javase/11/docs/api/java.base/java/util/concurrent/ThreadPoolExecutor.html] lets us tune some configurations like the following for releasing the unused resources
> * corePoolSize
> * keepAliveTimeMs
> * allowCoreThreadTimeOut
> Current code makes it difficult to pass along these configurations to the executor service. Refactor and fix the defaults for low-priority thread pools to release resources quicker.
