ClickHouse onKubernetes
In short: Running ClickHouse on Kubernetes means using the Altinity ClickHouse Operator to define sharded, replicated clusters via ClickHouseInstallation custom resources, which it materializes as StatefulSets with PersistentVolumeClaims and tiered storage. It coordinates replicas through ZooKeeper or ClickHouse Keeper and automates rolling upgrades, backups, and Prometheus monitoring.
Deploy production-grade ClickHouse on Kubernetes with the Altinity Operator, sharded clusters, columnar storage optimization, and cloud-native scaling for real-time analytics at petabyte scale.

Why Run ClickHouse on Kubernetes?
Cloud-native ClickHouse with operator-managed lifecycle, horizontal sharding, columnar compression, and infrastructure-as-code for consistent, repeatable analytics deployments.
Cloud-Native OLAP
Run ClickHouse as a first-class Kubernetes workload with declarative configuration, self-healing, and seamless integration with your cloud-native infrastructure and CI/CD pipelines.
Operator-Managed Lifecycle
The Altinity ClickHouse Operator encodes expert knowledge into automated controllers that handle provisioning, shard topology, schema management, and rolling upgrades without manual intervention.
Columnar Compression
ClickHouse's column-oriented storage with LZ4, ZSTD, and Delta codecs achieves 10-40x compression ratios, dramatically reducing storage costs for large-scale analytics workloads on Kubernetes.
Horizontal Sharding
Scale ClickHouse horizontally by adding shards to distribute data across more nodes. The operator manages shard topology declaratively, and Distributed tables route queries across the cluster.

Our ClickHouse on Kubernetes Implementation Process
A proven methodology for deploying production-ready ClickHouse on Kubernetes with comprehensive testing and validation.
Assessment & Planning
Evaluate your analytics workload requirements, data volumes, query patterns, and Kubernetes environment. Design the shard/replica topology, storage tiers, and ClickHouse Keeper ensemble.
Operator & Cluster Setup
Deploy the Altinity ClickHouse Operator via Helm. Configure ClickHouseInstallation custom resources, StatefulSets, persistent volumes, ZooKeeper/Keeper, and security contexts.
Migration & Validation
Migrate data from existing ClickHouse or analytics systems, validate schema and Distributed tables, perform query benchmarking, and test backup/restore procedures under load.
Production & Operations
Go live with full monitoring, alerting, automated backups, and runbooks. Provide team training on operator management, day-2 operations, and ongoing optimization support.
