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

    [ https://issues.apache.org/jira/browse/FLINK-12691?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16852951#comment-16852951 ] 

vinoyang commented on FLINK-12691:
----------------------------------

How do you plan to pass the capacity and timeout information to the {{RuntimeContext}} (then let it pass these parameters to the {{RichAsyncFunction as you side}})?

> 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.
