I started looking into TSID/KSUID/ULID in order to support cursor based pagination schemes in GraphQL against non-integer based unique id fields (such as uuids or unique string ids).
A couple of notable Java libs:

Sortable Collision-Free UUIDs

I've used something very similar in the past, called SimpleFlake[0], which is essentially a 64 bit version with the same principles. I've used it in Lisp, C, C++, Clojure, Python, and Rust. It's conceptually simple, and fits in a 64bit int, which is natively available in a lot of databases.
