Pulsar supports https://pulsar.apache.org/docs/en/cookbooks-tiered-storage/, Tiered storage, which is great. I experiment this feature, and saw it put some files on to AWS S3, looks like 2 files per segment, both with the same UUID:

  • 5780710b-393a-49cb-aff7-282901d7e311-ledger-9
  • 5780710b-393a-49cb-aff7-282901d7e311-ledger-9-index

I think it would be a mess later if there are many topics, and I cannot figure out which file belongs to which topic by the name. If I delete the topic use pulsar-admin, the files stay on AWS S3.

Is there a way to manage this?
