Anoop Sam John updated HBASE-10713: ----------------------------------- Fix Version/s: (was: 2.0.0) > 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 > Attachments: HBASE-10713_WIP.patch > > > 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. -- This message was sent by Atlassian JIRA (v6.3.4#6332)
