-----------------------------------

             Summary: Add an introduction about how to migrate DataSet API to DataStream
                 Key: FLINK-33041
                 URL: https://issues.apache.org/jira/browse/FLINK-33041
             Project: Flink
          Issue Type: Improvement
          Components: Documentation
    Affects Versions: 1.18.0
            Reporter: Wencong Liu
             Fix For: 1.18.0


The DataSet API has been formally deprecated and will no longer receive active maintenance and support. It will be removed in the Flink 2.0 version. Flink users are recommended to migrate from the DataSet API to the DataStream API, Table API and SQL for their data processing requirements.

Most of the DataSet operators can be implemented using the DataStream API. However, we believe it would be beneficial to have an introductory article on the Flink website that guides users in migrating their DataSet jobs to DataStream.
