Oscar Westra van Holthe - Kind commented on AVRO-3649:
------------------------------------------------------
I like this!
Especially as it adjusts default value handling and not the schema itself (so
the _parsing canonical form_ doesn't change).
> [JAVA] reorder union types to match default value

> The Avro specification requires that a default value matches the first schema
> of a union type.
>
> Using @Nullable on a field will return a union type of the form ["null",
> "<something>"].
> @Nullable also sets the default value to "null".
>
> It is not possible to override this default value w{color:#172b4d}ith
> @AvroDefault because of the order of the schemas in the generated
> union.{color}
>
> It would be nice that union types are automatically reordered to match the
> type of the provided default value.
