I’d very highly recommend watching
https://www.youtube.com/watch?v=4fFDFbi3toc. They were running 10 million scenarios per night to test the thing when they were a startup I can only imagine what they were able to do with Apple’s resources. Given the approach they use it’s extremely likely it actually is the most reliable and tested distributed KV store.

I think the biggest difference is that FoundationDB supports ACID with linearizable consistency. It also seems to have some limited relational support.

it’s an ordered KV store. You can use it as a storage layer for RDBMS and my understanding is that there is SQL RDBMS that uses foundationDB but it was not open sourced by Apple. I bet FoundationDB will get picked up by various projects as underlying storage engine so hopefully we will see in not too distant future a number of SQL RDBMS using FoundationDB as a storage layer. Would be cool if it was PostgreSQL but it’s unlikely because it doesn’t have pluggable storage engines.

So it’s more like Riak then? Riak uses leveldb to distribute commands amongst a quarom of nodes that can be dynamically added/removed.

Yep but it’s ACID and explicitly designed to be a storage layer for a higher level database. They wrote toy implementation of SQLite on top of FoundationDB in a day. Plus again thanx to the way they have developed the thing it’s most likely the most reliable distributed KV store.
