I was just looking into using KafkaAvroSerializer to produce records to a Kafka topic. We are interested because the wire format has a reference to the schema so we don’t have to schema lookup information independently.
We plan to keep a single topic that contain records using many different schemas (it’s important to maintain the ordering of these records). In looking at the code, it appears that it registers the schema with the registry with a topic+”-topic” subject. This would seem to imply an assumption that a topic has a single schema associated with it (not many schemas that can vary from record to record). Am I understanding this correctly? It seems like a surprising constraint.
