David Alves commented on DRILL-13:
----------------------------------
I know this might be a bit too much detail for now but we should track bloom
filter capabilities of the underlying engine e.g. HBase can have ROW and
ROW_COL bloom filters and Cassandra Key bloom filters.
Being able to know they exist, which points in the schema they pertain to and
extract them from the underlying store is very interesting to optimize a series
of use cases.
