    Can you give more examples on the sharding_key other than rand() in the distributed table? In case I add new shard to the cluster, how to rebalance the existing data and/or the new incoming data based on the disk usage of the nodes? Thanks!

      sharding key could be any field which will have better data locality, customer_id for SaaS as an example, currently, re-balancing data part is not supported, but you can subscribe to github.com/CIickHouse/ClickHouse/issues/13574 and watch to discussion

    Good talk. can we use distributed over the normal tables(without replication) without running the zookeeper?

      Yes. Distributed tables just depend on the server names in the tag in config.xml. They do not require access to Zookeeper for queries.
