@Enclosing public class SplitPythonConditionFromCorrelateRule extends org.apache.calcite.plan.RelRule<SplitPythonConditionFromCorrelateRule.SplitPythonConditionFromCorrelateRuleConfig>
Rule will split a FlinkLogicalCalc which is the upstream of a FlinkLogicalCorrelate and contains Python Functions in condition into two FlinkLogicalCalcs. One of the FlinkLogicalCalc without python function condition is the upstream of the FlinkLogicalCorrelate, but the other FlinkLogicalCalc with python function conditions is the downstream of the FlinkLogicalCorrelate. Currently, only inner join is supported.

After this rule is applied, there will be no Python Functions in the condition of the upstream FlinkLogicalCalc.
