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

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 level log messages for profiling and debugging.
