      Hey #avro specialists, can someone tell me what the selected word below (which happens to be "selected" 😅) means? http://avro.apache.org/docs/current/spec.html#Schema+Resolution …pic.twitter.com/IcDwwAmuDI

      Hard to tell without more context but I would say that it means "If your writer schema is defined as "type": ["typeA", "typeB"], and you happen to use typeA to write a specific field then you can read said field with if your reader is a reader for "type":"recordA".

      But this is in the context of comparing schemas with one another (what's called "schema resolution" in the spec, cf the link in my tweet), so it feels like "selected" is meaningless here.

      I think it was a case of I'd like to use magnolia if it supported everything avro4s does already. One use case I'm not sure is supported in magnolia is default value literals.

      Do you mean defaults on case class parameters?

          Yes, `case class Foo(name: String = "sam")` Avro4s will support `case class Foo(name: String = Bar.method)` as well but that's probably a use case too far.

          Magnolia supports car class parameter defaults, and they don't have to be static. :)
