Gali Sheffi updated HBASE-19506: -------------------------------- Attachment: HBASE-19506-V04.patch > Support variable sized chunks from ChunkCreator > ----------------------------------------------- > > Key: HBASE-19506 > URL: https://issues.apache.org/jira/browse/HBASE-19506 > Project: HBase > Issue Type: Sub-task > Reporter: Anastasia Braginsky > Priority: Major > Attachments: HBASE-19506-V01.patch, HBASE-19506-V02.patch, > HBASE-19506-V03.patch, HBASE-19506-V04.patch > > > When CellChunkMap is created it allocates a special index chunk (or chunks) > where array of cell-representations is stored. When the number of > cell-representations is small, it is preferable to allocate a chunk smaller > than a default value which is 2MB. > On the other hand, those "non-standard size" chunks can not be used in pool. > On-demand allocations in off-heap are costly. So this JIRA is about to > investigate the trade of between memory usage and the final performance. -- This message was sent by Atlassian JIRA (v7.6.3#76005)
