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)
