>
> 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.
