[jira] [Created] (FLINK-12691) Make Queue Capacity and Timeout of AsyncWaitOperator changeable during runtime

Konstantin Knauf created FLINK-12691:
----------------------------------------

             Summary: Make Queue Capacity and Timeout of AsyncWaitOperator changeable during runtime
                 Key: FLINK-12691
                 URL: https://issues.apache.org/jira/browse/FLINK-12691
             Project: Flink
          Issue Type: Improvement
          Components: API / DataStream
            Reporter: Konstantin Knauf


A user that I have recently been working with has the requirement to change the capacity and possibly the timeout during the runtime of a job. 

Conceptually, this should be possibly by just passing these parameters to the {{RichAsyncFunction}} via its RuntimeContext. The change of the timeout would only apply to future records and the change in the queue capacity would take effect immediately.
