Manual Re-authentication

[connoranderson]

I've been reading #4301 which describes SASL re-authentication triggered by broker-side configuration. For my use-case, I have a need to trigger re-authentication on the producer side, due to an issue where AWS MSK does not close connections once credentials have expired. When this happens, the producer is essentially stuck unable to fetch metadata for the topic for many hours until a REAUTH is triggered naturally.

When credentials expire, we receive Broker: Topic authorization failed in the producer, which allows me to easily create application code to handle this. I've tried manually triggering token refreshes, but unfortunately re-authentication does not occur simultaneously with token refreshes.

Any suggestions for how to proceed?

@emasab maybe you could help direct this to the right person at Confluent?
