> A MemStore implementation with in memory flushes to CellBlocks
> --------------------------------------------------------------
>
> Key: HBASE-10713
> URL: https://issues.apache.org/jira/browse/HBASE-10713
> Project: HBase
> Issue Type: New Feature
> Reporter: Anoop Sam John
> Assignee: Anoop Sam John
> Fix For: 0.99.0
>
>
> 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.
