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
