Maximilian Michels commented on BEAM-5299:
------------------------------------------
That is exactly the type of lookup I had in mind. I had added the timestamp to
the enum value extension but this felt rather hacky. The {{beam_urn}} extension
is applicable to every transform, the max timestamp value only applies to
PAR_DO and ASSIGN_WINDOW, but ideally it should be a global constant.
I'm not sure what the best point is to encode a proto-wide constant.
> Define max global window as a shared value in protos like URN enums.
