> OOM regression caused by Batched DoFn worker changes
> ----------------------------------------------------
>
> Key: BEAM-14481
> URL: https://issues.apache.org/jira/browse/BEAM-14481
> Project: Beam
> Issue Type: Bug
> Components: sdk-py-core
> Reporter: Brian Hulette
> Priority: P1
> Time Spent: 0.5h
> Remaining Estimate: 0h
>
> We've observed some OOMs in internal pipelines. We've narrowed the root cause
> down to [https://github.com/apache/beam/pull/17384] - the worker changes for
> Batched DoFns.
> I still don't understand the root cause, but given this change can lead to a
> regression in pipelines that don't use the feature I think we should roll it
> back.
