We also published it as a crate https://crates.io/crates/segcache

What’s your billing model?

Congrats! Although I look back fondly on the many years I spent on debugging cache incidents ( https://danluu.com/cache-incidents/ ) I don’t think the rest of the world should go t…

Hello! I still have your cookie jar LOL

Hopefully we can open source our deployment "generator" sometime soon. It's not gonna work in AWS (Twitter isn't a cloud first company) but you will get the basic idea. Yes, swappa…

It was supposed to be a bit tongue-in-cheek... Obviously nobody should create a pingserver just for the sake of with the specs we had. But, as a halfway marker to a production-read…

They are not quite the same thing. Pelikan has the building blocks for an RPC server, storage, wire protocols, data structures, and whatever code that is needed to glue these toget…

I assume you meant this as a comparison against Segcache? We touched upon the CLOCK-Pro a bit in related work of the paper ( https://www.usenix.org/system/files/nsdi21-yang.pdf , S…

It's a SaaS startup offering managed cache (like Elastic Cache). They have their own protocol but uses Pelikan-segcache as one of their backends.

I'm a big fan of their fountain pens and the piston filling mechanism.

Project creator here, didn't expect to see the link on HN :P Here's the latest code architecture diagram: https://raw.githubusercontent.com/pelikan-io/pelikan-io.gith... And a slig…

Oh the link broke when I changed the permanent URL format after the post was published. Here is the correct link: https://twitter.github.io/pelikan/2016/separation-concerns.h... I'…

Disclosure: I'm maintainer/author of Pelikan. I wrote about Pelikan, a unified cache framework, and its relationship to Memcached and Redis in this blog from 2019: https://twitter.…

Here’s a blog version of the paper for anybody who isn’t into 12 page double column pdf files https://twitter.github.io/pelikan/2021/segcache.html

Internally I’ve written a generator to spit out a deploy config based on input vectors such as (qps, data size, connections). But it assumes using Twitter’s container environment. …

lol I'm glad you asked there since I am on HN about once every 3 months...

Based on his response on Twitter I'd guess not https://twitter.com/dormando/status/1381706098290225152 But also agree with you that in that high concurrency usually not needed when…

The nature of tech work means employees generally have more flexibility with their time, and can afford such involvement without jeopardizing their productivity or job. It is thus …

I don't work on GraphDB, but basically the situation is this: 1) yes, it is not a great use case for MySQL, but that's how it started, partly because Twitter needed join on its gra…

In general, Twitter infrastructure didn't start by building solutions in house. Like most early stage companies, it started by using whatever it can find in the OSS repertoire. But…
