Charles Chen commented on BEAM-3759:
------------------------------------
What I believe is not done is emission of PaneInfo in the Python implementation
of GBK (either in the Python FnAPIRunner or the old Python DirectRunner /
triggers.py).
> Add support for PaneInfo descriptor in Python SDK

> The PaneInfo descriptor allows a user to determine which particular
> triggering emitted a value. This allows the user to differentiate between
> speculative (early), on-time (at end of window) and late value emissions
> coming out of a GroupByKey. We should add support for this feature in the
> Python SDK.
