Anoop Sam John resolved HBASE-10713.
------------------------------------
Resolution: Duplicate
Assignee: (was: Anoop Sam John)
Closing as a dup of HBASE-14918. There we are doing conceptually the same..
Instead of CellBlock as flat byte[], we have Segments there which can be cell
array or cell chunk with index. HBASE-14918 is almost getting to its closure.
> A MemStore implementation with in memory flushes to CellBlocks

> After HBASE-10648 we can plugin any implementation for MemStore. This issue
> aims at coming up with an implementation, in which we will have in between in
> memory flushes. This will reduce the need to keep lots of KVs in heap as well
> as in CSLM. CSLM perform poor when no# items in it increases. We can keep
> create CellBlocks (contigous byte[] like HFile block) out of KVs and keep it
> as one object rather than many KVs. At some point in time, MemStore might
> have N CellBlocks and one CSLM.
> These in memory CellBlocks can be compacted to one bigger block in between.
> We can target that in follow on tasks once the basic code is ready.
