---------------------------------
Summary: Support extracting source mapping for all RexNode
Key: FLINK-31404
URL: https://issues.apache.org/jira/browse/FLINK-31404
Project: Flink
Issue Type: Sub-task
Components: Table SQL / Planner
Affects Versions: 1.17.0, 1.17.1
Reporter: Jane Chan
Currently, `StreamNonDeterministicUpdatePlanVisitor` only supports extracting a
limited kind of RexNode to its input node for the Calc.
* RexInputRef
* RexCall with the operator kind as `AS` and `CAST`
It can be optimized to support all kinds of RexNode by
FlinkRexUtil#findAllInputRefs.
