Re: Red Hat contributes etcd to the Cloud Native Computing Foundation
#22etcd has succeeded as a piece of distributed systems infrastructure beyond our wildest expectation. When Alex Polvi, Xiang Li, and I started the project as a README in the summer of 2013 we identified that their still was no consensus database that was developer friendly, easily secured, production ready, and based on a well understood consensus algorithm. And largely we got lucky with good market timing, the inventi…
Docker Swarm Mode also embeds etcd.
(The embedding mechanism is copy-paste, which I find both ingenious and a bit distasteful. Maybe I’m just sore I didn’t think of it first)

#23This is exactly the kind of thing that should be a layer on top of FoundationDB. Too many state stores all doing largely the same thing.
FoundationDB has only been open source for 8 months?? etcd is like 5 years old.

Are you sure? I’ve spent quite some time playing with the internals of Docker Swarm / swarmkit last year and I’m quite confident it wasn’t true then. As far as I know they call go-raft directly because they only need a fraction of the features offered by etcd.

zookeeper uses a coordination kernel, while etcd uses a replicated state machine.

It uses etcd/raft from beginning.
