---------------------------------

             Summary: [Chore] Separate the execution period between CompactionChecker and PeriodicMemStoreFlusher
                 Key: HBASE-22596
                 URL: https://issues.apache.org/jira/browse/HBASE-22596
             Project: HBase
          Issue Type: Improvement
            Reporter: Reid Chan
            Assignee: Reid Chan


The story started at tuning RS performance where I found:
{code}
public static final String THREAD_WAKE_FREQUENCY = "hbase.server.thread.wakefrequency";
...
this.threadWakeFrequency = conf.getInt(HConstants.THREAD_WAKE_FREQUENCY, 10 * 1000);
...
this.compactionChecker = new CompactionChecker(this, this.threadWakeFrequency, this);
this.periodicFlusher = new PeriodicMemStoreFlusher(this.threadWakeFrequency, this);
{code}
CompactionChecker and PeriodicMemStoreFlusher execution period are bound together. (as well as LeaseChecker)

This issue is going to introduce two new parameters such that user/admin can tune them according to business workload.
