Dave Latham commented on HBASE-18165:
-------------------------------------
[~apurtell], sounds great! Would that cover this predicate-based deletion also?

> Project: HBase
> Issue Type: Brainstorming
> Reporter: Lars Hofhansl
>
> In many cases it is expensive to place a delete per version, column, or
> family.
> HBase should have way to specify a predicate and remove all Cells matching
> the predicate during the next compactions (major and minor).
> Nothing more concrete. The tricky part would be to know when it is safe to
> remove the predicate, i.e. when we can be sure that all Cells matching the
> predicate actually have been removed.
> Could potentially use HBASE-12859 for that.
