[jira] [Created] (FLINK-14202) Optimize the execution plan for Python Calc when there is a condition

Dian Fu created FLINK-14202:
-------------------------------

             Summary: Optimize the execution plan for Python Calc when there is a condition
                 Key: FLINK-14202
                 URL: https://issues.apache.org/jira/browse/FLINK-14202
             Project: Flink
          Issue Type: Sub-task
          Components: API / Python
            Reporter: Dian Fu
             Fix For: 1.10.0


As discussed in [https://github.com/apache/flink/pull/9748]:

"For the filter, we calculate these condition UDFs together with other UDFs and do the filter later. I think we can optimize it a bit, i.e., calculate the conditions first and then check whether to call the other UDFs. This can be easily achieved in the SplitRule."
