Sandeep Tata commented on CASSANDRA-77:
---------------------------------------
Yes, this is part of a bigger feature: range queries on column names :-)
Much like you'd want to support range queries on keys, range queries on columns
can be useful too -- eg: get all columns between 'a' and 'c' or get all columns
starting with 'f', etc.
I think Jun is working on the other pieces to support the rest of this, the
RangeFilter is just an easy subtask I wanted to get out of the way.
> Need RangeFilter that filters by column name so that min <= name <= max
