> 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:
