Chubby. It was the product that inspired Zookeeper and all its various incarnations, including etcd.

Ah, the attempt to claim credit for something that likely wasn’t inspired by Chubby at all.

etcd was inspired by a hash-map more so than Chubby.

etcd didn’t work initially; I wouldn’t call it polished.

It worked, it had a bug.
