Anoop Sam John commented on HBASE-18056: ---------------------------------------- Reduction in GC when there are duplicated data right? PE kind of work load where each of the data is diff key, how come this merge will reduce GC? > Change CompactingMemStore in BASIC mode to merge multiple segments in pipeline > ------------------------------------------------------------------------------ > > Key: HBASE-18056 > URL: https://issues.apache.org/jira/browse/HBASE-18056 > Project: HBase > Issue Type: Sub-task > Reporter: Anastasia Braginsky > > Under HBASE-16417 it was decided that CompactingMemStore in BASIC mode should > merge multiple ImmutableSegments in CompactionPipeline. Basic+Merge actually > demonstrated reduction in GC, alongside improvement in other metrics. > However, the limit on the number of segments in pipeline is still set to 30. > Under this JIRA it should be changed to 1, as it was tested under HBASE-16417. -- This message was sent by Atlassian JIRA (v6.3.15#6346)
