StefanRRichter opened a new pull request #9034: [FLINK-13063] Temporary fix for AsyncWaitOperator consistency problems.
URL: https://github.com/apache/flink/pull/9034
 
 
   ## What is the purpose of the change
   
   This PR is a temporary fix for the consistency problems with the `AsyncWaitOperator` that are described under FLINK-13063. This temporary fix works simply by deactivating all chaining for `AsyncWaitOperator`.
   
   
   ## Brief change log
   
   Set the chaining strategy in the constructor of `AsyncWaitOperator` to `NEVER` by default.
   
   
   ## Verifying this change
   
   This change is already covered by existing tests. I added an additional test that chaining is suppressed by default and also check that users could go back to the old (broken) behavior if they had to, by setting the chaining strategy manually on the operator.
