ClickHouse is a popular open-source database management system that can be expensive to run in its default configuration due to high storage costs. To manage cost and achieve better performance, ClickHouse users can configure the database to use a hybrid approach with durable object storage and ephemeral local storage. This allows for cheap, durable storage while caching actively queried records in fast, ephemeral local storage, achieving a better price/performance ratio. By moving data to object storage like Amazon S3, which is 84% cheaper than traditional EBS volumes, users can significantly reduce their storage costs. However, they need to be aware of potential high latency and API costs associated with object storage. To set up this hybrid approach, ClickHouse users can use Kubernetes and the clickhouse-operator to deploy and manage their database in a scalable and efficient manner. With proper configuration, users can achieve cost savings of up to 40% by separating storage and compute, achieving storage elasticity, and reducing latency.
