> Kafka consumers stores in state only kafka offsets and doesn't store last emmited watermarks,
this may go to wrong state when checkpoint is restored:
> Let's say our watermark is (timestamp - 10) and in case we have the following messages
queue results will be different after checkpoint restore and during normal processing:
> A(ts = 30)
> B(ts = 35)
> ------ checkpoint goes here
> C(ts=15) -- this one should be filtered by next time window
> D(ts=60)
