Patrick Wendell updated SPARK-911:
----------------------------------

    Description: 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.  (was: \[Tentatively assigned to me, but anyone can do 
this if they'd like!\]
