[jira] [Created] (FLINK-33941) Use field index instead of field name about window time column

xuyang created FLINK-33941:
------------------------------

             Summary: Use field index instead of field name about window time column
                 Key: FLINK-33941
                 URL: https://issues.apache.org/jira/browse/FLINK-33941
             Project: Flink
          Issue Type: Technical Debt
          Components: Table SQL / Planner
            Reporter: xuyang


In some exec nodes like StreamExecGroupWindowAggregate and some rules like BatchPhysicalWindowAggregateRule, planner uses "AggregateUtil#timeFieldIndex" to access the actual time field index, instead of using the time field index in LogicalWindow#timeAttribute directly. However, it would be more formal to use the field index instead of the column field.
