Liyin Tang commented on HBASE-4469:
-----------------------------------
@Jonathan,
For this jira specifically, it has been committed to 89-fb internal branch
before cutting the public 89-fb branch.
So it should already in the public 89-fb right now.
> Avoid top row seek by looking up bloomfilter

> The problem is that when seeking for the row/col in the hfile, we will go to
> top of the row in order to check for row delete marker (delete family).
> However, if the bloomfilter is enabled for the column family, then if a
> delete family operation is done on a row, the row is already being added to
> bloomfilter. We can take advantage of this factor to avoid seeking to the top
> of row.
