Clickhouse

ClickHouse is a high-performance open-source columnar OLAP database built for real-time analytics.

Kubernetes Deployment​

I use Altinity ClickHouse Operator on Kubernetes:

The Altinity Kubernetes Operator for ClickHouse creates, configures and manages ClickHouse clusters running on Kubernetes.

  • Creates ClickHouse clusters defined as custom resources
  • Customized storage provisioning (VolumeClaim templates)
  • Customized pod templates
  • ClickHouse cluster scaling including automatic schema propagation
  • Exporting ClickHouse metrics to Prometheus
