Thanks for the KIP, Andrew. I'm all for making the client more robust against networking and deployment weirdness
I'm not sure I fully grok the scenario you are covering here. It sounds like you're guarding against a hostname being reused by a different broker. Does the client not learn about the new broker hostnames when it refreshes metadata periodically? -David On Thu, Nov 20, 2025 at 5:59 AM Andrew Schofield <[email protected]> wrote: > Hi, > I would like to start discussion of a new KIP for detecting and handling > misrouted connections from Kafka clients.
