Hi currently I'll need to run pyflink udf on python 3.9 which is not supported right now
I tried building - pyarrow==2.0.0 - apache-beam==2.27.0 on python 3.9 and test python jobs but failed Is there any discussions/git branch on python 3.9 before? (I didn't find any in this dev list) so I can continue working to fit 3.9
