Date Fri, 14 Mar 2014 10:27:46 GMT

Anoop Sam John commented on HBASE-10648:
----------------------------------------

bq.Sorry but what's preventing the change to go into 94?The CSLM issue (when there are too
many KVs in it) also exists in v94, and we also want to get relieved from that Of course I'm
not expecting the whole HBASE-10191 solution go into 94, but after making Memstore impl pluggable,
at least in-memory flush impl would fit well in 0.94, right?
Ping [~larsh] abt the decision.

> Make Memstore into an interface implementation.  Also make it pluggable by configuring
the FQCN of the impl.
> This will allow us to have different impl and optimizations in the Memstore DataStructure
and the upper layers untouched.
