Tommy Becker commented on KAFKA-5886:
-------------------------------------

Thanks for the response. Though the KIP may be an improvement, I think this 
behavior where sends to a perfectly functioning cluster are dropped is clearly 
a bug, and I'd argue a major one. We have a use case where we are reading from 
a local file and producing the records to Kafka and even with 
{{request.timeout.ms = 120000}} and {{max.in.flight.requests.per.connnection = 
1}} it is still dropping records.

> Introduce delivery.timeout.ms producer config (KIP-91)

> We propose adding a new timeout delivery.timeout.ms. The window of 
> enforcement includes batching in the accumulator, retries, and the inflight 
> segments of the batch. With this config, the user has a guaranteed upper 
> bound on when a record will either get sent, fail or expire from the point 
> when send returns. In other words we no longer overload request.timeout.ms to 
> act as a weak proxy for accumulator timeout and instead introduce an explicit 
> timeout that users can rely on without exposing any internals of the producer 
> such as the accumulator.
