Does anyone know of cool things built with fdb? I’ve been aware of it for a while and it seems very cool but I haven’t seen a lot of details about how folks are using it.

Apple uses it for CloudKit. I'd say that's pretty cool. Snowflake uses it for their metadata layer. Datadog uses it for their system called Husky (https://www.datadoghq.com/blog/engineering/introducing-husky...)

It looks like people are using it to build graph related models on it.

I am looking at it & considering doing something similar for graph data sets. As well as a transactionally safe key value store to store roaring bitmaps.

I am moving my SaaS from RethinkDB to FoundationDB. It's a long-term project that needs to be done very carefully (thousands of people using the app), but the rewards are significant. Thanks to FoundationDB versionstamps, I'll be able to replace changefeeds with polling, simplifying the system, and also make things much faster along the way.

The consistency guarantees are phenomenal and writing software is much easier when you have strict serializability. Most people do not appreciate this because they do not understand the anomalies that you can get without strict serializable consistency.

Also in this same exact boat.

An abandoned project I'd love to see resurrected is SQLite on fdb: https://github.com/losfair/mvsqlite

I'm excited by the idea of pgfdb*. I think it could be a great. postgres, with foundation replacing the transaction system to provide all the benefits that brings, horizontal scalability, automatic sharding, replication, and fault tolerance, and performance. foundationdb is 20+ years ahead of postgres in terms of distributed transaction theory.

Arroyo uses it for their streaming database. Think streaming stateful aggregations. It’s pretty cool tech. Looks like they were recently acquired by cloudflare.

ecto_foundationdb makes it easy to use FDB with Elixir, providing indexes, on-line migrations, and multitenancy.

I use it as the DB layer for LiveSecret.

From what I understand one of the big IP ad tracking services (El Toro) is built on FoundationDB.

Cognite built their dataplatform with foundationdb.
