Hello! This is a very general question but I was wondering if anyone knows whether or not the Kafka brokers need to do any additional work to receive/respond to requests coming in from older clients.
Even though newer brokers support older clients, is there any additional processing time that can be incurred because of the version mismatch. I'm specifically curious about the Kafka brokers 0.9.x responding to Kafka clients 0.8.2. Thank you. Waleed
