Lars Hofhansl commented on HBASE-5268:
--------------------------------------
I'll work on a fully correct patch today, and then we can decide whether it is
worth the extra complexity. I find this first patch compelling, because (1) is
very small and easy to verify and (2) it keeps column prefix delete markers
sorted (by timestamp) with the KVs they affect.
In the bigger patch, neither will be try anymore.

> This is another part missing in the "wide row challenge".
> Currently entire families of a row can be deleted or individual columns or
> versions.
> There is no facility to mark multiple columns for deletion by column prefix.
> Turns out that be achieve with very little code (it's possible that I missed
> some of the new delete bloom filter code, so please review this thoroughly).
> I'll attach a patch soon, just working on some tests now.
