----------------------------------------
Discussed with [~apurva]. We are currently thinking that we will just clarify
in the documentation which errors should be treated as fatal. I will submit a
patch shortly.
> Distinguish abortable failures in transactional producer

> The transactional producer distinguishes two classes of user-visible errors:
> 1. Abortable errors: these are errors which are fatal to the ongoing
> transaction, but which can be successfully aborted. Essentially any error in
> which the producer can still expect to successfully send EndTxn to the
> transaction coordinator is abortable.
> 2. Fatal errors: any error which is not abortable is fatal. For example, a
> transactionalId authorization error is fatal because it would also prevent
> the TC from receiving the EndTxn request.
> At the moment, it's not clear how the user would know how they should handle
> a given failure. One option is to add an exception type to indicate which
> errors are abortable (e.g. AbortableKafkaException). Then any other exception
> could be considered fatal.
