While using Flink Stateful functions is there a simple approach to handle multiple message types from the same kafka ingress topic

I have multiple message types being consumed from the same Kafka topic ingress. While I can extend the message types to a 'wrapper' super class then downcast them after they are de-serialized, this does not seem like a good option. Are there any alternatives?

what SDK are you using? if you are using remote functions you can simple get the raw bytes of a message and handle serialization in your functions. If you are using the embedded SDK, you can still achieve that by using a payload (for example Protobuf Any) – Igal May 31 '21 at 09:50
thanks for the suggestion Igal. Will try the protobuf any option – cal Jun 03 '21 at 04:17
