> Project: Apache Apex Core
> Issue Type: Improvement
> Affects Versions: 3.4.0
> Reporter: Vlad Rozov
> Assignee: Vlad Rozov
> Fix For: 3.4.0
>
>
> When all active input ports of an operator are empty, the operator either
> calls idle time handler or goes into a wait. In the later case, the wait time
> should start with 0 and increase to the configured/default idle spin time to
> handle cases when there is trickle and pour stream of tuples.
