Next time the protocol is evolved and new error codes can be introduced, would it make sense to add a new one called "Deprecated" (or "Deprecation" or "DeprecatedOperation" or whatever sounds best)? This would act as a more precise form of "Unknown" error. It could help identify what the problem is more easily when debugging clients.
Of course, this is the kind of lever one would prefer never pulling, but when you need it, you're better off having it than not, and if you end up having it and never using it, it does not do much harm either. -- Felix GV Data Infrastructure Engineer Distributed Data Systems LinkedIn f...@linkedin.com<mailto:f...@linkedin.com> linkedin.com/in/felixgv<http://linkedin.com/in/felixgv> ________________________________ From: kafka-clie...@googlegroups.com [kafka-clie...@googlegroups.com] on behalf of Magnus Edenhill [mag...@edenhill.se] Sent: Thursday, January 15, 2015 10:40 AM To: dev@kafka.apache.org Cc: kafka-clie...@googlegroups.com Subject: [kafka-clients] Re: Heads up: KAFKA-1697 - remove code related to ack>1 on the broker I very much agree on what Joe is saying, let's use the version field as intended and be very strict with not removing nor altering existing behaviour without bumping the version. Old API versions could be deprecated (documentation only?) immediately and removed completely in the next minor version bump (0.8->0.9). An API to query supported API versions would be a good addition in the long run but doesn't help current clients much as such a request to an older broker version will kill the connection without any error reporting to the client, thus making it rather useless in the short term.
