Jonathan Gray commented on HBASE-2823:
--------------------------------------
I think I like #1. Seems like the most minimally invasive way to do this.
There's virtually no impact on memory consumption, hfile size/complexity,
etc... The cost will be doing two bloom checks, however bloom operations are
constant time so I suspect the impact to be negligible.
> Entire Row Deletes not stored in Row+Col Bloom

> Key: HBASE-2823
> URL: https://issues.apache.org/jira/browse/HBASE-2823
> Project: HBase
> Issue Type: Bug
> Components: filters, regionserver
> Affects Versions: 0.21.0
> Reporter: Nicolas Spiegelberg
> Fix For: 0.21.0
>
>
> If the user issues a Row Delete on an family with Row+Col blooms, that
> information is not currently detected by shouldSeek(). Possible known
> solutions are:
> 1. adding Row as Bloom Filter Key on Row Delete, shouldSeek() should do both
> a Row & Row+Col query for Row+Col filters.
> 2. keep delete information in a separate storage element.
> #1 seems like the best solution, but need to investigate further and fix this
> problem.
