jmullins opened a new pull request #304: AVRO-2067: Add object-value attrs to
PropBuilder
URL: https://github.com/apache/avro/pull/304
Add object-value attribute support to SchemaBuilder.PropBuilder:
public final S prop(String name, Object value)
JsonProperties supports object-valued attributes through its
addProp() and getObjectProps() methods. Extend SchemaBuilder.PropBuilder
to also support object-valued attributes so that schemas with non-string
attributes can be created programmatically.

> Add object-value attribute support to _SchemaBuilder.PropBuilder_.
> {code:java}
> public final S prop(String name, Object value)
> {code}
> The avro 1.8.2 specification permits the use of undefined schema
> attributes as metadata:
> {quote}
> "Attributes not defined in this document are permitted as metadata, but must
> not affect the format of serialized data."
> {quote}
>
> The permitted types of attribute values is unclear from the above, but
> attributes with object values (non-string) are supported when parsing a
> schema and in the JsonProperties base class from which both Schema and
> Schema.Field inherit.
>
> _JsonProperties_ supports object-valued attributes through its _addProp()_
> and _getObjectProps()_ methods.
> In our use case, we need to programmatically normalize and augment
> user-supplied schemas which may contain attributes with object values like
> booleans and arrays of strings. The absence of a method in
> _SchemaBuilder.PropBuilder_ which support object-valued attributes makes this
> difficult.
