> Compiler needs to track the original TS key columnName used for MJ probedecode.
> Even though we know the MJ keyCol at compile time, this could be generated by previous
(parent) operators thus we dont always know the original TS column it maps to.
> To find the original columnMapping, we need to track the MJ keyCol through the operator
pipeline. Tracking can be done through the parent operator ColumnExprMap and RowSchema.
