Boyang Chen commented on KAFKA-9913:
------------------------------------
I'm fine with combining the two tickets in one KIP as this saves the KIP review
iteration. [~guozhang] Could you reflect this ticket in the KIP title as well?
Something like `Augment TopologyDescription with serde information and
programmatic interface`
> TopologyDescription should expose all topic name progrematically

> During the discussion of KIP-594, it became clear that it is helpful for
> testing purpose to verify which topics are used in a topology (ie, all user
> input and output topics, as well as internal topics like repartiton or
> changelog topics).
> While the current `TopologyDescription` does expose this information (only
> changelog topic names are missing atm), there is no convenient way to get all
> topic names at once, but one must traverse the nodes of each sub-topology to
> collect this information manually.
> Hence, the proposal is to add utility methods to `TopologyDescription` that
> expose this information programatically. As this is a public API change, it
> will be required to write a KIP
