Yes, the delete topic feature itself is much stable now. However, there are a couple of limitations. (1) If there is a running consumer, the topic will be auto-created again since currently a TopicMetadataRequest triggers a topic creation. (2) The associated consumer offsets associated with the deleted topic are not removed. So, if the topic gets re-created again, the consumer may get an unexpected offset. We have jiras to address both issues. Perhaps we can change the default setting for enabling topic deletion after those are addressed?
