changed the title
This change allows to list buckets by pure prefix with the parameter `IterParams.WithoutAppendDirDelim`. This allows to list huge "directories" more efficently and in parallel. Together with lexographical ordering of ULID certain time stamps can be listed. Outstanding tasks: - [ ] Implement this for filesystem - [ ] Test coverage - [ ] Implement for other providers than azure/gcs/s3 Signed-off-by: Christian Simon <[email protected]>

This change allows to list buckets by prefix with the parameter
IterParams.WithoutAppendDirDelimis set, without appending a/in the end.This allows to list huge "directories" bit by bit and in parallel. It is quite useful to list a huge amount of ULID (or other lexicographical ordered keys).
This would allow to preselect a creation time of blocks by e.g. listing
/01H19*ULIDs, we would only list blocks created between2023-05-25T08:21:51.744Zand2023-05-25T17:41:06.175Z.Before I spend more time on this, I wonder how people are feeling about it and if this useful for others.
