-------------------------------------
Summary: Support takeOrdered and topK values per key
Key: SPARK-10405
URL: https://issues.apache.org/jira/browse/SPARK-10405
Project: Spark
Issue Type: Improvement
Components: Spark Core
Reporter: ashish shenoy
Spark provides the top() and takeOrdered() APIs that return "top" or "bottom"
items from a given RDD.
It'd be good to have an API that returned the "top" items per key for a keyed
RDD i.e. RDDpair. Such an API would be very useful for cases where the task is
to only display an ordered subset of the input data.
