Anoop Sam John commented on HBASE-16421: ---------------------------------------- Use the new config 'hbase.regionserver.offheap.global.memstore.size' which says the global off heap memstore size. (Size in MBs) We still need 'hbase.regionserver.global.memstore.size' also which says the heap % for max global size. Also to make sure that the system using MSLAB and pool. hbase.hregion.memstore.mslab.enabled -> True hbase.hregion.memstore.chunkpool.maxsize -> 1 These configs def value only Also pls make sure that HBASE_OFFHEAPSIZE is having appropriate value (hbase-env.sh).. Need to add some more than the global off heap memstore size (Like 2 GB or so). The ByteBufferPool at RPC layer uses off heap memory. Also the NIO layer need some off heap memory as well. > Introducing the CellChunkMap as a new additional index variant in the MemStore > ------------------------------------------------------------------------------ > > Key: HBASE-16421 > URL: https://issues.apache.org/jira/browse/HBASE-16421 > Project: HBase > Issue Type: Umbrella > Reporter: Anastasia Braginsky > Priority: Major > Attachments: CellChunkMapRevived.pdf, ChunkCell_creation.png, > IntroductiontoNewFlatandCompactMemStore.pdf > > > Follow up for HBASE-14921.
