Hmm, I would have thought this would already work? If you refresh metadata for a topic that has been deleted, you should presumably get back Oh, I guess this fix is only needed for the refresh-all case? It seems like polling the specific topic would be more efficient for your client anyway? But I suppose this PR is still more correct. |

Yeah, this is only in the refresh all case, and I should actually just poll for the specific topic 😅, but this seems like undesired behaviour. |

There was a problem hiding this comment.

Currently, If you list topics, then delete a topic, and poll to find out when the topic is actually deleted, it will never appear as deleted.
This is because
updateMetadatadoesn't remove topics that no longer exist from the metadata.An example can be seen over at terraform-provider-kafka
Here's a very naive solution that deletes the previous metadata, if you've got all the topic information from the broker.
