Subject [jira] [Created] (HBASE-18056) Change CompactingMemStore in BASIC mode to merge multiple segments in pipeline

-------------------------------------------

             Summary: 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.
