https://github.com/apache/incubator-apex-core/pull/287
apexcore-407 adaptive spin millis for input operators
I tested change with the benchmarking and I can clearly see the improvement
in performance. It is similar to what was done before
https://issues.apache.org/jira/browse/APEXCORE-380
https://github.com/apache/incubator-apex-core/pull/271
Performance numbers increased from <710000 tuples/sec to >10,00,000
tuples/sec.
This change was reviewed by @vrozov, closed the old one as Travis build was
failing.

> 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.
