Hi everyone, I would like to start the discussion about marking SourceFunction-based interfaces as deprecated. With the FLIP-27 APIs becoming the new standard, the old ones have to be eventually phased out. Although this state is well known within the community and no new connectors based on the old interfaces can be accepted into the project, the footprint of SourceFunction in the user code still keeps growing (primarily for data generators and test utilities). I believe it is best to mark SourceFunction as deprecated as soon as possible. What do you think?
Best, Alexander Fedulov
