1) Kubernetes operators can simplify deploying data warehouses like ClickHouse from a single specification and provide portability, fast deployment, and flexible resource management. 2) While the Kubernetes operator model reduces overhead, ensuring data safety remains a challenge as data warehouses are complex and losing data is problematic. 3) Future work includes developing data warehouses as a service on Kubernetes with multi-tenancy, high availability, security, and optimized resource utilization, as well as enhancing ClickHouse to better match Kubernetes' cloud-native execution model.
