Eshcar Hillel commented on HBASE-15016:
---------------------------------------
Sure it would help if you have a clean version.
As a matter of fact perhaps a clean version of your patch is all that is needed
for this sub-task, while the flush policy which is tightly coupled with
compacting memstores and additional changes to column descriptor like adding
isCompacting() method should be part of sub-task #3 where we actually declare
the new class.
What do you say?

> The default implementation of a memstore ensures that between two flushes the
> memstore size increases monotonically. Supporting new memstores that store
> data in different formats (specifically, compressed), or that allows to
> eliminate data redundancies in memory (e.g., via compaction), means that the
> size of the data stored in memory can decrease even between two flushes. This
> requires memstores to have access to facilities that manipulate region
> counters and synchronization.
> This subtasks introduces a new region interface -- StoreServices, through
> which store components can access these facilities.
