Kafka topic - Compare previous message with a new message

I would like to implement a functionality in my scala and kafka stream application.

Every message I receive in kafka has a “id” or “name” key attribute and a “status” in the avro schema. So for every message I receive I would like to check the “status” of each “id” and whenever a “Id” has it’s “status” changed from previous message to a different “status” in new message send that record to a output topic
