Maximilian Michels commented on BEAM-5299:
------------------------------------------
DoFns are free to return WindowedValues with GlobalWindow, but they don't have
a notion of the Proto (e.g. at least in the JAVA SDK when you look at
{{WindowedValue}}). So instead of using a concrete timestamp for the global
window, we would have to use a placeholder which gets translated into a lookup
at runtime.
I'm leaning more towards documenting and fixing the global max timestamp value
in all SDKs which doesn't seem that hard.
Any thoughts on this [~lcwik]?
> Define max global window as a shared value in protos like URN enums.
