I have not thought about making KafkaRecord 'schema' like good point. There are some consequences on that that are still not clear to me (like how will we deal with the runtime resolution part of Schemas for KV that we do now with the Confluent Schema Registry support. I am going to give it a try and ping you once I have something in the other PR #10978. Let's continue that discussion there. ---------------------------------------------------------------- This is an automated message from the Apache Git Service.
