  • Plan B for UUIDs: double AES-128

    I really like ULID for this problem (e.g: https://github.com/ahawker/ulid)

    - same number of bytes as UUID

    - start with a date, so has great locality. Plus you get extra information in the uid that you can extract.

    - can be created from an existing date or uuid, and exported to a uuid, so there is a migration path

  • New UUID Formats from IETF

    As the author of a popular ULID implementation in python[1], the spec has no stewardship anymore. The specification repo[2] has plenty of open issues and no real guidance or communication beyond language implementation authors discussing corner cases. The monotonic functionality is ambiguous (at best) and is implemented differently per-languages [3].

    Functionality, UUIDv7 might be the _same_ but the hope would be for a more rigid specification for interoperability.

  • Sortable Collision-Free UUIDs

    Looks similar to ULID[0] (I am the author of a popular python implementation[1]).

    It appears to have a similar constraint that two ID's generated within the same timestamp (ms, ns) have no strong guarantee of ordering. That might not be a deal breaker depending on your use case but something to consider.
