Looks nice, I will definitely be trying this out.

Built in s3 storage immediately sold me. I’ve used something called Exhibitor to manage ZK clusters in the past but it’s totally dead. Working with ZK is probably one of my least favorite things to do.

I used exhibitor in the past too. They were specially useful during the time when zookeeper cluster needed to expand/shrink or move host nodes. Zookeeper dynamic configuration solved that problem, which seems to be also supported by clickhouse keeper, Pretty impressive! Would definitely give it a try.

It does indeed.

Do note the docs page...

In particular, it is necessary to enable the `keeper_server.enable_reconfiguration` flag. It is pretty exhaustive coverage but if there is an important use case missing, let us know!
