Jonathan Gray commented on HBASE-4469:
--------------------------------------

What is the protocol now?  This needs to go into the fb-89 branch, so do I keep 
this JIRA open until that happens, or should we just add some fb-89-pending tag 
or something?

> 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.
