             Summary: Replace inter.broker.protocol.version with KIP-35 based version detection
                 Key: KAFKA-3724
                 URL: https://issues.apache.org/jira/browse/KAFKA-3724
             Project: Kafka
          Issue Type: Bug
            Reporter: Gwen Shapira


inter.broker.protocol.version configuration was nice for few releases, but it is getting to be a pain to maintain, remember to update, it breaks on trunk upgrades, etc.

Since we have KIP-35, the controller can actually check for specific versions supported by brokers for specific API requests. Why not use that and get rid of the configuration? 

We already maintain the protocol versions anyway, upgrades will be smoother, and we'll support upgrades between any two patches.
