Daniel Dai updated PIG-3010: ---------------------------- Fix Version/s: (was: 0.12.0) 0.13.0 > 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: 0.13.0 > > Attachments: PIG-3010-0.patch, PIG-3010-1.patch, > PIG-3010-2_nowhitespace.patch, PIG-3010-2.patch, PIG-3010-3_nows.patch, > PIG-3010-3.patch, PIG-3010-4_nows.patch, PIG-3010-4.patch, > PIG-3010-5_nows.patch, PIG-3010-5.patch > > > 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 was sent by Atlassian JIRA (v6.1#6144)
