Ordered events in broadcast state

[Filip Niksic <fn...@seas.upenn.edu>]

Hi all,

The documentation for the broadcast state explicitly says that the order of
broadcast events may differ across tasks, so the state updates should not
depend on a particular order. [1] But what to do in the use cases where the
order matters? Is there some way to enforce the order even at the expense
of performance, or are such use cases out of scope for Flink?
