Hi Martjin and Luan, As of now, the main reason why PyFlink has not declared to support Python 3.9 is that the dependent apache-beam, and the versions of numpy and pyarrow that apache-beam depends on do not provide corresponding whl packages in Python 3.9. Users need source code installation, but source code installation is really difficult to install successfully, especially pyarrow. If you can successfully install these dependencies on python3.9 through source installation, as far as I know, you can successfully run the pyflink job. We are also upgrading the versions of these dependencies[1], and then we can easily provide support for python 3.9 and Mac M1.
