Those seem like standard needs for any kind of CRUD app, so I would call this approach pretty useful. Currently I do something similar by keeping a private primary uuidv7 key with a btree index (a sortable index), and a separate public uuidv4 with a hash index (a lookup index), which is a workable but annoying arrangement. This solution achieves the same effect and is simpler.

Why can't you leak timestamp data? What timestamp data is sensitive to your system?

Also, why use UUIDs in that case?
