Hi all! I would suggest to deprecating the existing python APIs for DataSet and DataStream API with the 1.9 release.
Background is that there is a new Python API under development. The new Python API is initially against the Table API. Flink 1.9 will support Table API programs without UDFs, 1.10 is planned to support UDFs. Future versions would support also the DataStream API. In the long term, Flink should have one Python API for DataStream and Table APIs. We should not maintain multiple different implementations and confuse users that way. Given that the existing Python APIs are a bit limited and not under active development, I would suggest to deprecate them in favor of the new API. Best, Stephan
