> If someone has sorted a (K, V) rdd, we should offer them a way to filter a range of the
partitions that employs map pruning. This would be simple using a small range index within
the rdd itself. A good example is I sort my dataset by time and then I want to serve queries
that are restricted to a certain time range.
