Jonathan Coveney created PIG-3010: ------------------------------------- Summary: Allow UDF's to flatten themselves Key: PIG-3010 URL: https://issues.apache.org/jira/browse/PIG-3010 Project: Pig Issue Type: Improvement Reporter: Jonathan Coveney Assignee: Jonathan Coveney Fix For: 0.12
This is something I thought would be cool for a while, so I sat down and did it because I think there are some useful debugging tools it'd help with. The idea is that if you attach an annotation to a UDF, the Tuple or DataBag you output will be flattened. This is quite powerful. A very common pattern is: a = foreach data generate Flatten(MyUdf(thing)) as (a,b,c); This would let you just do: a = foreach data generate MyUdf(thing); With the exact same result! -- This message is automatically generated by JIRA.
