> It is not currently possible to delete a range of columns without retrieving the range
through the thrift interface and then deleting the columns by name. An efficient implementation
of this is dependent on, but it can at
least be accomplished server-side in the current implementation so as to avoid the overhead
of the client-side communication. I'm going to attach one proposed implementation that adds
a remove_range_slices api method for parallelism with get_range_slices, but i'm not wedded
to either the implementation nor the particular api.
