Todd Lipcon commented on HBASE-2450:
------------------------------------
The bloom filter seems like a pretty decent approach. Given we expect only
something <1% deletions, it should be only a couple hundred KB per 1GB region
worth of bloom data for a very low false positive rate.
> For single row reads of specific columns, seek to the first column in HFiles
> rather than start of row
