Duo Zhang commented on HBASE-17360:
-----------------------------------

It is a nice to have. Will have a try, but if we can not make it in time then 
it is OK to move it out I think.

Thanks.

> As discussed in HBASE-17177, we can record a compacted mvcc for each 
> storefile, and use an inmemory data structure to track it. If we get a scan 
> request with an mvcc in place, we can use this value to determine if we can 
> guarantee the given consistency level.
