Hi everyone, following the discussion in [1], I would like to open up a vote for deprecating the SourceFunction API.
An overview of the steps required for being able to drop this API in the next major version is maintained in the umbrella FLINK-28045 ticket [2]. This proposition implies marking the SourceFunction interface itself as @Deprecated + redirecting to the FLIP-27 Source API right away, without waiting for all the subtasks to be completed.
