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:
