Michael Stack commented on HBASE-20711:
---------------------------------------
Move old issue that still seems legit but that is having no work being done out
of its parent issue.
> Save on a Cell iteration when writing

> This is a minor savings. We were doing a spin through all Cells on receipt
> just to check their size when subsequently, we were doing an iteration of all
> Cells to insert. It manifest as a little spike in perf output. This change
> removes the purposed spin through Cells and just does size check as part of
> the general Cell insert (perf spike no longer shows but the cost of the size
> check still remains).
> There is also a minor bug fix where on receipt we were using the Puts row
> rather than the Cells row; client may have succeeded in submitting a Cell
> that disagreed with the hosting Mutation and it would have been written as
> something else altogether -- with the Puts row -- rather than being rejected.
