Umesh Agashe commented on HBASE-16549:
--------------------------------------
I have summarized AMv2 metric changes in the doc:
https://docs.google.com/document/d/1gJsjlacYRuFCSrp8q1zNRr8oWrel339rUtdmFuV7PxE/edit?usp=sharing.
Grouping related details like batch size for remote dispatch etc should not be
exposed through metrics. We can add trace() messages for profiling and
debugging.
