Hi, Flink dev community, I'd like to contribute to Flink. Particularly, I am interested in kinds of optimization works in Flink.
To be familiar with the process of contribution, I pick up some starter issue as the entrance contribution(s) such as [FLINK-5692]( https://issues.apache.org/jira/browse/FLINK-5692) and/or some else. It is appreciated who gives me the permission of that I can assign that issue to myself. Then, the journey can be started:) best regards, Jin
