> The producer should retry expired batches when retries are enabled

>
> Today, when a batch is expired in the accumulator, a {{TimeoutException}} is
> raised to the user.
> It might be better the producer to retry the expired batch rather up to the
> configured number of retries. This is more intuitive from the user's point of
> view.
> Further the proposed behavior makes it easier for applications like mirror
> maker to provide ordering guarantees even when batches expire. Today, they
> would resend the expired batch and it would get added to the back of the
> queue, causing the output ordering to be different from the input ordering.
