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

             Summary: HBASE-20564 Tighter ByteBufferKeyValue Cell Comparator part 2
                 Key: HBASE-20620
                 URL: https://issues.apache.org/jira/browse/HBASE-20620
             Project: HBase
          Issue Type: Sub-task
          Components: Performance
    Affects Versions: 2.0.0
            Reporter: stack
            Assignee: stack
             Fix For: 2.0.1


This is a follow-on from HBASE-20564 "Tighter ByteBufferKeyValue Cell Comparator". In this issue, we make a stripped-down comparator that we deploy in one location only, as memstore Comparator. HBASE-20564 operated on CellComparator/Impl and got us 5-10k more throughput on top of a baseline 40k or so. A purposed stripped-down ByteBufferKeyValue comparator that fosters better inlining gets us from 45-50k up to about 75k (1.4 does 110-115k no-WAL PE writes). Data coming. Log of profiling kept here: https://docs.google.com/document/d/1vZ_k6_pNR1eQxID5u1xFihuPC7FkPaJQW8c4M5eA2AQ/edit#
