[jira] [Created] (FLINK-3989) Add guide to write a custom streaming source / sink in DataStream API documentation

Tzu-Li (Gordon) Tai created FLINK-3989:
------------------------------------------

             Summary: Add guide to write a custom streaming source / sink in DataStream API documentation
                 Key: FLINK-3989
                 URL: https://issues.apache.org/jira/browse/FLINK-3989
             Project: Flink
          Issue Type: Task
          Components: Documentation
    Affects Versions: 1.1.0
            Reporter: Tzu-Li (Gordon) Tai


I think it's a good idea to add a basic outline in the documentation for users to compose their own streaming connector source / sinks, as its quite a frequently asked question in the mailing lists and might be helpful for Flink to get traction on new external systems faster.

The documentation should contain information about what classes to extend, what life cycle methods to implement, how to implement an exactly once source, etc.
