-----------------------------------
Summary: Fast single-node in-memory shuffle
Key: SPARK-15690
URL: https://issues.apache.org/jira/browse/SPARK-15690
Project: Spark
Issue Type: New Feature
Components: Shuffle, SQL
Reporter: Reynold Xin
An increasing number of Spark users are using the system to process data on a
single-node. When in a single node operating against intermediate data that
fits in memory, the existing shuffle code path can become a big bottleneck.
Ideally, Spark should be able to use in-memory radix sort to do data shuffling
on a single node
