-----------------------------------------
Summary: Massive regression on 20.06.2021
Key: FLINK-28241
URL: https://issues.apache.org/jira/browse/FLINK-28241
Project: Flink
Issue Type: Bug
Reporter: Anton Kalashnikov
In FLINK-27921 added property `REQUIREMENTS_CHECK_DELAY` that optimizes the
number of checks of resources but it also leads to a little delay during the
init phase which is totally not critical for the normal scenario. But
unfortunately, our benchmarks can not exclude the time of the initial phase(or
shutdown phase) from the total time of benchmarks. As result, all benchmarks,
that have a relatively short execution time(compare to the initial phase time),
have regression(up to 50%). As a quick solution, it makes sense just to set
`REQUIREMENTS_CHECK_DELAY` to zero for all benchmarks.
Not full list of affected benchmarks:
* asyncWait
* globalWindow
* mapSink
* readFileSplit
* remoteRebalance
* serializer*
* sorted*
* twoInputOneIdleMapSink
