> Priority: Major
>
> In [https://kafka.apache.org/protocol#protocol_types,] we didn't specify the
> encoding of a struct. In particular, how a nullable struct is represented. We
> should document that if a struct is nullable, the first byte indicates
> whether is null and the rest of the bytes are the serialization of each field.
