Mark Wagner commented on PIG-3325:
----------------------------------
Cool. Thanks, Rohini!
Dmitriy, what was your LoadFunc? I found that if the LoadFunc creates bags with
an initial list of elements, then the slowness doesn't show up until later when
new bags are created (during a DISTINCT in my case).

> Key: PIG-3325
> URL: https://issues.apache.org/jira/browse/PIG-3325
> Project: Pig
> Issue Type: Bug
> Affects Versions: 0.11, 0.11.1, 0.11.2
> Reporter: Mark Wagner
> Assignee: Mark Wagner
> Priority: Critical
> Attachments: PIG-3325.demo.patch, PIG-3325.optimize.1.patch

> The time it takes to add a tuple to a bag has increased significantly,
> causing some jobs to take about 50x longer compared to 0.10.1. I've tracked
> this down to PIG-2923, which has made adding a tuple heavier weight (it now
> includes some memory estimation).
