> Looking at the java doc comment of SchemaProvider it hints at getting
> schema's from external system. But as the provider only access type this is
> in general impossible:
> Say you have 2 dynamic types, say Avro, as a java type they have both
> GenericRecord. Using the current interface it's impossible to make the
> difference between both dynamic types.
> As getting information from an external system I propose extending the
> Provider interface by adding an extra parameter to the interface. It would be
> a string with a URN.
> The URN could indicated for example
> * Pub/Sub subscription/topic
> * Kafka topic
> * whatever...
