Kurt Young commented on FLINK-6097:
-----------------------------------
What is the purpose of keep the field order? And when function calls, what is
the order of the parameters? Like {{select func(a, b, c) from t}}, should the
order be {{a, b, c}} or {{c, b, a}}
> Guaranteed the order of the extracted field references

> The current `ProjectionTranslator # identifyFieldReferences` method uses the`
> Set` temporary save field, causing the field to be out of order, although the
> out of order is also working, but I think the order is better than out of
> order. So I want to improve it,Orderly extraction field.
