> 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.
