Description

Scalar Python UDF (FLIP-58) has already been supported in release 1.10 and Python UDTF will be supported in the coming release of 1.11. In release 1.10, we focused on supporting UDF features and did not make many optimizations in terms of performance. Although we have made a lot of optimizations in master, Cython can further greatly improve the performance of Python UDF.
