Nicolas Spiegelberg commented on HBASE-1200:
--------------------------------------------
Sorry. Patch n00b. I did svn mv
src/java/org/apache/hadoop/hbase/io/HalfHFileReader.java
src/java/org/apache/hadoop/hbase/io/HalfStoreFileReader.java & apparently that
doesn't reflect well in my svn diff output. This worked for me, but may not be
the kosher way to do it:
{{
svn cp src/java/org/apache/hadoop/hbase/io/HalfHFileReader.java
src/java/org/apache/hadoop/hbase/io/HalfStoreFileReader.java
patch -p0 < HBASE-1200-0.20.5-4.patch
svn rm src/java/org/apache/hadoop/hbase/io/HalfHFileReader.java
}}

> Add bloomfiltering to hfile. Can be enabled on a family-level basis.
> Ability to configure a row vs row+col level bloom. We size the bloomfilter
> with the number of entries we are about to flush which seems like usually
> we'd be making a filter too big, so our implementation needs to take that
> into account.
