Returning error when server is not available

[purplefox]

Hi,

I am using the message producer to send a message, providing a delivery channel and then I block on the channel, waiting for the result.

I've noticed that when the target Kafka server is unavailable, instead of returning an error on the delivery channel, the client seems to retry to connect to the server forever.

My application is non blocking and needs to know quickly (within a few ms) whether the produce succeeded or failed, so it can go and do other stuff.

I've tried to configure "reconnect.backoff.ms", "reconnect.backoff.max.ms" and "retry.backoff.ms" but these don't seem to have any effect.

Can you tell me how to configure the client so it doesn't retrying connecting and returns an error straightaway?
