Production Cluster Configuration Guide

Moving from a single ClickHouse server to a clustered format provides several benefits:

  • Replication guarantees data integrity.
  • Provides redundancy.
  • Failover by being able to restart half of the nodes without encountering downtime.

Moving from an unsharded ClickHouse environment to a sharded cluster requires redesign of schema and queries. Starting with a sharded cluster from the beginning makes it easier in the future to scale the cluster up.

Setting up a ClickHouse cluster for a production environment requires the following stages:

  • Hardware Requirements
  • Network Configuration
  • Create Host Names
  • Monitoring Considerations
  • Configuration Steps
  • Setting Up Backups
  • Staging Plans
  • Upgrading The Cluster
