Hi devs, I would like to start a discussion on FLIP-344: Remove parameter in RichFunction#open [1].
The open() method in RichFunction requires a Configuration instance as an argument, which is always passed as a new instance without any configuration parameters in AbstractUdfStreamOperator#open. Thus, it is unnecessary to include this parameter in the open() method. As such I propose to remove the Configuration field from RichFunction#open(Configuration parameters). Looking forward to your feedback. [1] https://cwiki.apache.org/confluence/pages/viewpage.action?pageId=263425231 Best regards, Wencong Liu
