stack commented on HBASE-20806:
-------------------------------
Sounds great. Task manager has seen no love. Here maybe where that changes.
BTW, hbase2 flushes are now at least on par w hbase1 after some work. What
will the log look like?

> In 1.x we have split transaction journal that gives a clear picture of when
> various stages of splits took place. We should have a similar thing for
> flushes and compactions so as to have insights into time spent in various
> stages, which we can use to identify regressions that might creep up.
