On: MinIO repository is no longer maintained

I didn't find an alternative that I liked as much as MinIO and I, unfortunately, ended up creating a my own. It includes just the most basic features and cannot be compared to the larger projects, but is simple and it is efficient.

The listing is perhaps in line with the first two "s". It seems it always iterates through all files, reads the "meta.json", then filters?

Yes, indeed. The list operation is expensive. The S3 spec says that the list output needs to be sorted.

1. All filenames are read. 2. All filenames are sorted. 3. Pagination applied.

It doesn't scale obviously, but works ok-ish for a smaller data set. It is difficult to do this efficiently without introducing complexity. My applications don't use listing, so I prioritised simplicity over performance for the list operation.

Maybe mention it somewhere as a limitation, so it is not used for use-cases where listing is important and there are many objects?

Listing was IMO a problem with minio as well, but maybe it is not that important because it seems to have succeeded anyway.
