Review comment:
That's because DoFnOperator actually generates a bundle in `dispose`. That
looks really funky at maybe should be looked at separately.

> Key: BEAM-5760
> URL: https://issues.apache.org/jira/browse/BEAM-5760
> Project: Beam
> Issue Type: Improvement
> Components: runner-flink
> Affects Versions: 2.8.0

> Priority: Major

> Fix For: 2.9.0

> Time Spent: 2h

> The portable runner needs to support larger bundles in streaming mode.
> Currently every element is a separate bundle, which is very inefficient due
> to the per bundle SDK worker overhead. The old Java SDK runner already
> supports these parameters.
