Subject [jira] [Commented] (FLINK-6097) Guaranteed the order of the extracted field references
Date Fri, 17 Mar 2017 09:23:41 GMT

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.
