[jira] [Created] (HBASE-17765) Reviving the merge possibility in the CompactingMemStore

Anastasia Braginsky created HBASE-17765:
-------------------------------------------

             Summary: Reviving the merge possibility in the CompactingMemStore
                 Key: HBASE-17765
                 URL: https://issues.apache.org/jira/browse/HBASE-17765
             Project: HBase
          Issue Type: Sub-task
            Reporter: Anastasia Braginsky


According to the new performance results presented in the HBASE-16417 we see that the read latency of the 90th percentile of the BASIC policy is too big due to the need to traverse through too many segments in the pipeline. In this JIRA we correct the bug in the merge sizing calculations and allow pipeline size threshold to be a configurable parameter.
