> 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.
