Liang Xie created HBASE-9678:
--------------------------------

             Summary: evaluate/compare the current on heap memstore impl with a native in-memory
map
                 Key: HBASE-9678
                 URL: https://issues.apache.org/jira/browse/HBASE-9678
             Project: HBase
          Issue Type: Brainstorming
          Components: regionserver
            Reporter: Liang Xie
            Assignee: Liang Xie


Though current MemStoreLAB works well, it's still worth to write a native map prototype(like
accumulo's), then compare two things at least:
1) gc benifit
2) write/read perf degradation

if the choice one is good enough, then we could introduce a config at least, for some clusters
which don't need best write/read speed, but more prefer stable respone time or throughput
w/o gc hurt, then it's a cadidate.
