python-ksuid VS ksuid

Homepage: https://www.svix.com

It's really fast, it makes writing secure and correct code easier, it's easier to deploy and distribute (one static binary), and it's a lot more fun. :)

Webhooks are really cool, and I absolutely love what they enable. They make the web compose-able, interconnected, and enable people to automate a lot of their work! Our goal is to make them easy, reliable, and consistent, so that more services offer them and they are easier to consume.

I'd love to hear your feedback! We've incorporated most of the comments we got the last time[0] (thanks again everyone!), and we would love to know how we can improve the product further. Got any suggestions?

I wasn't going to post it here because it feels a bit small for a show HN, but then I figured: why not. :)

It's a pure Rust implementation of Segement's KSUID, and I created this library while working on Svix[0].

I haven't written any Rust for a while, so even though I have written quite a bit of Rust code in the past (see Etebase[1]), I'm a bit rusty (no pun intended).

Anyhow, I just wanted to share, and I'm hoping to get some feedback if you have any. :)

P.S, the package is tested for compatibility against the reference Go implementation.

I created this library while working on Svix. We have a highly scalable and distributed environment there, which is where KSUIDs really shine.

These reasons are exactly why we started Svix[1] (we do webhooks as a service). I wish we existed to serve you guys back when you started working on it. :)

Hey everyone, my name is Tom, and I'm the founder of Svix (https://www.svix.com) - previously known as Diahook. Svix makes it easy for developers to send webhooks from their service using a simple API. Think Twilio or SendGrid but for webhooks.

Webhooks are how servers notify each other of events, so they are a key component of many APIs such as Stripe, Shopify, Slack, Dropbox and Github.

OP here - we avoid sequences in all but one part of our application due to a dependency. We use [KSUIDs][1] and UUID v4 in various places. This one "gotcha" applies to any sequence, so it's worth calling out as general advice when running a migration like this.

UUID v4 isn't large enough to prevent collisions, that is why segment.io created https://github.com/segmentio/ksuid which is 160bit vs the 128bit of a UUIDv4.

Assuming you don't need to use UUIDv7 (or any UUID's) then https://github.com/segmentio/ksuid provides a much bigger keyspace. You could just append a string prefix if you wanted to namespace, but the chance of collisions of a KSUID is many times smaller than a UUID of any version.

KSUID's are have temporal-lexicographical order plus 128 bits of entropy, which is more than UUIDv4.

That's why you use ksuid (https://segment.com/blog/a-brief-history-of-the-uuid/) or, if you're willing to go with a draft spec you could go with the new UUID formats https://www.ietf.org/archive/id/draft-ietf-uuidrev-rfc4122bi...

Interesting in more history of UUIDs? Twilio Segment's blog has an amazing history lesson about how they came to be.

I use the ksuid from segment. https://github.com/segmentio/ksuid
