From: Aliaksandr Pliutau ClickHouse cluster is a homogenous cluster. Steps to set up:
-1. Install ClickHouse server on all machines of the cluster
-2. Set up cluster configs in configuration file
-3. Create local tables on each instance
-4. Create a Distributed tableClickHouse deployment to cluster

Distributed-table is actually a kind of "view" to local tables of ClickHouse cluster. SELECT query from a distributed table will be executed using resources of all cluster's shards. You may specify configs for multiple clusters and create multiple Distributed-tables providing views to different clusters.
