Hello, I have been playing with kafka producer and consumer. I have created different topics at different times with different replica and partition options.
After 7 days of un-use, list-topics script does not list the unused topic. However, I can see the log and index files for such topic partitions still exist on the file system. If I publish to such a topic, since auto.create.topics.enable=true, a new topic is created with default partition=1 since num.partitions=1 and no replication. This seems like a bug to me. I expect the the old messages may be purged as per property setting for log retention, however the topic should still exist and remember its original configuration for # of partitions and replication. How does it work behind the scenes? Thanks, Priya
