Aaron commented on SPARK-911:
-----------------------------
I was just wondering about this when answering
http://stackoverflow.com/questions/24677180/how-do-i-select-a-range-of-elements-in-spark-rdd,
I noticed that RangePartitioner stores an array of upper bounds, but I was
unsure from the docs if that meant that the each partition had no overlap in
range. If they don't this seems like it would be a pretty easy feature to
implement
> Support map pruning on sorted (K, V) RDD's

> 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.
