Bye Sequence, Hello UUIDv7

1. ksuid

   1 39 5,110 3.1 Go

   K-Sortable Globally Unique IDs

   

   Feels like a spiritual successor to the ksuid [1] lib which I first heard of used in conjunction with DynamoD.

   [1]: https://github.com/segmentio/ksuid which has very similar use cases.

2. InfluxDB

   InfluxDB – Built for High-Performance Time Series Workloads. InfluxDB 3 OSS is now GA. Transform, enrich, and act on time series data directly in the database. Automate critical tasks and eliminate the need to move data externally. Download now.

   

3. cuid2

   2 20 3,030 2.8 JavaScript

   Next generation guids. Secure, collision-resistant ids optimized for horizontal scaling and performance.

   

   There's a comparison in the README of the project:

   https://github.com/paralleldrive/cuid2#the-contenders

   Some of the arguments mentioned are explained elsewhere in the README, others are assumed.

   One argument standing out for me is the lack of collision-resistance for UUIDv4 which is surprising for me and I didn't spot any sources for that argument.

   Another argument is the entropy source where they go about that Math.random is not reliable as a single entropy source but glimpsing at the source code, they sprinkle the CUID with Math.random data.

   I am no expert in ID security, so I am not qualified to speak about the validity of their arguments, only that there's insufficient information to validate without prior knowledge about the problem domain.

4. pg_idkit

   3 10 400 9.0 Dockerfile

   Postgres extension for generating UUIDs

   

   Yup this is one of the reasons I put together a light extension for this:

   https://github.com/VADOSWARE/pg_idkit

   There are a lot of options for UUID extensions (lots of great pure SQL ones!), but I wanted to get as many ID generation strategies in one place

   Also note that native UUID v7 is slated to land in pg17:

   https://commitfest.postgresql.org/44/4388/

5. spec

   4 66 10,299 0.0

   The canonical spec for ulid

   

6. postgresql-uuid-generate-v7

   5 1 58 2.8 PLpgSQL

   

   If it helps anyone, at work, I open sourced the UUID v7 postgresql function that I wrote: https://github.com/Betterment/postgresql-uuid-generate-v7

   We've seen some amazing benefits, especially around improving the speed of batch inserts.
