> In never ending quest to make Pig go faster, we want to parallelize as many relational operations as possible. Its already possible to do Group-by( PIG-984 ) and Joins( PIG-845 , PIG-554 ) purely in map-side in Pig. This jira is to add map-side implementation of Cogroup in Pig. Details to follow.
