Josh Wills commented on AVRO-1274:
----------------------------------
Hey Tom-- I wrote something along these lines way back in the day:
https://github.com/jwills/avroplay/blob/master/src/com/randomgraphs/avro/RecordSchemaBuilder.java
The general orientation is towards supporting the union { null, T } pattern for
optional fields w/default values, and it ends up looking like:
Schema schema = new RecordSchemaBuilder("myrecord")
.requiredString("foo")
.optionalFloat("bar", 17.29f)
.array("baz", Schema.create(Schema.Type.STRING))
.build();
It has support for default values for primitive types and just wraps them in
JsonNodes as need be, and is smart about checking to see if your record is
named or anonymous. I'm happy to re-format it as a patch if you think it's
worthwhile. My main feeling was that the name, type, and required/optional
nature of the field are the three things you really always have to know, and
whether/not you have a doc string or sort order info should be hidden away as
rarely-used options in this context.
