broker-stats will list the topics which are loaded by the current broker. So if you create the partitioned topic but without loading it (create producer/consumer), it can’t be listed. Even if you use the topics partitioned-stats.

broker-stats will list the topics which are loaded by the current broker.

Note that this is also true for the /metrics endpoint, which is typically used for collecting prometheus metrics.
