Anything in my life that uses Zookeeper or its dumbass etcd friend means I'm going to have a real bad time. I am thankful they're at least shipping their own ZK-ish but it seems to have fallen into the same trap as etcd, where membership has to be managed like the precious little pets that they are https://clickhouse.com/docs/guides/sre/keeper/clickhouse-kee...

Zookeeper in the only clustering product I’ve ever used that actively refused to start a cluster after an all-nodes stop/start.

It blows my mind that a high availability system would purposefully prevent availability as a “feature”.
