Duo Zhang commented on HBASE-16225:
-----------------------------------

I test some of the UTs locally, some of them can not pass, but not sure if it relates to the
patch. Let me dig.

> As said in HBASE-16223, the code of {{ScanQueryMatcher}} is too complicated. I suggest
that we can abstract an interface and implement several sub classes which separate different
logic into different implementations. For example, the requirements of compaction and user
scan are different, now we also need to consider the logic of user scan even if we only want
to add a logic for compaction. And at least, the raw scan does not need a query matcher...
we can implement a dummy query matcher for it.
> Suggestions are welcomed. Thanks.
