>
> In Kafka 0.9.0 error codes were added to the topic commands. However, often
> users only want to perform an action based on the existence of a topic. And
> they don't want to error if the topic does or does not exist.
> Adding if-exists option for the topic delete and alter commands and
> if-not-exists for the create command allows users to build scripts that can
> handle this expected state without error codes.
