Ten years of ClickHouse in open source
Summary
This post marks a decade since ClickHouse went open source, detailing its origins from early prototypes to a production-grade, distributed analytics database. It covers major architectural milestones (columnar storage, MergeTree, compression and data processing pipelines), the move to open development with community contributions and ZooKeeper-based coordination, and the release process that invited the world to contribute. It also includes a reflection on the impact on the data-analytic ecosystem and a call for engineers to consider open-sourcing their work.
