---------------------------------
Summary: Update ElementByteSizeObservableIterable
Key: BEAM-9878
URL: https://issues.apache.org/jira/browse/BEAM-9878
Project: Beam
Issue Type: Improvement
Components: runner-dataflow
Reporter: Kyle Weaver
It's odd that ElementByteSizeObservableIterable::iterator adds observers within
the method body. I assume this is for historic reasons, since it doesn't seem
to do anything now, and the comment documenting references a setObserver method
that doesn't exist.
