What you say is true, clustering clickhouse is hard. But we are happy in a very different way. What used to be 6+6 cluster of graphite is now served by a single clickhouse instance handling millions of unique metric datapoints everyday, that we haven't even had the need to cluster it yet. It's an order of magnitude difference in performance & cost. Scale, but just in a different way, not just horizontal but holistically. Maybe when we need to cluster, we'll face the same issues.
