OiOStream has only one thread operating on it, why is there a need for
separate counts or issue with reset?
> Collision between Sink.getCount() and SweepableReservoir.getCount()

> Reporter: Vlad Rozov
> Assignee: Vlad Rozov
> Fix For: 3.4.0
>
>
> SweepableReservoir.getCount() and Sink.getCount() are two distinct counts as
> SweepableReservoir.getCount() returns number of tuples consumed/poll from the
> reservoir by an operator since the last reset, while Sink.getCount() returns
> number of tuples pushed into the sink since the last reset. For InlineStream
> that implements both interfaces, it causes a conflict as a count of tuples
> pushed into InlineStream is not necessarily equal to a count of tuples poll
> from it.
