------------------------------------
Summary: Support Cython Optimizing Python User Defined
Function(FLIP-121)
Key: FLINK-17115
URL: https://issues.apache.org/jira/browse/FLINK-17115
Project: Flink
Issue Type: Improvement
Components: API / Python
Reporter: Huang Xingbo
Fix For: 1.11.0
Scalar Python UDF
([FLIP-58|https://cwiki.apache.org/confluence/display/FLINK/FLIP-58%3A+Flink+Python+User-Defined+Stateless+Function+for+Table])
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.
