Mike Drob commented on HBASE-20781:
-----------------------------------
bq. Pushed to branch-2.0+. Thanks for review [~Apache9].
I only see this on branch-2 and master, not -2.0 or -2.1 -- need additional
backports here?
> Save recalculating families in a WALEdit batch of Cells

> Doing a doMiniBatchMutate, we calculate the set of families that the WALEdit
> Cells belong to up front but down after the RingBuffer when we make an
> FSWALEdit, we spin through all the Cells again to figure the set of families
> in a particularly painful way. Just pass the calculated family set in the
> WALEdit.
