Koji Noguchi commented on PIG-4212:
-----------------------------------
One of our users has a logic in their script that requires LIMIT on 0.
This user wants to store at most N outputs total from contentA and contentB.
Giving preference on contentA.
{noformat}
limitContentA = limit contentA N;
groupedContent_A = GROUP limitContentA ALL;
limitContentB = limit contentA N - totalStoredContent_A.$0
... store both limitContentA and limitContentB
{noformat}
> Allow LIMIT of 0 for variableLimit (constant 0 is already allowed)
