--------------------------------
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.
