@i-arge Checkout this article which describes Schema References. You’ll need to register the Timestamp schema separately and then refer to the Timestamp schema with a schema reference when registering the EventProto schema. As an FYI in Confluent Platform 6.2 this will not be required as Schema Registry will be aware of that google timestamp type natively.
