	tl;dr: ClickHouse, released as open source on June 15, 2016, grew out of creator Alexey Milovidov's prototypes (OLAPServer and Metrage) built at Yandex starting in 2008-2009 to handle web analytics workloads that existing databases couldn't manage. Unlike most modern databases built atop Postgres, DataFusion, or others, ClickHouse was written entirely from scratch, evolving through column storage, aggregate functions, MergeTree, and ZooKeeper-based replication before its public release. Ten years on, it has 2,000+ contributors and is one of the most popular open-source analytical databases.
	HN Discussion: ↑ClickHouse delivers superior performance and replaces multiple tools in users' stacks ~Regret over missing early adoption due to organizational bias against Russian-made software ↓Article omits key context like DuckDB as a rival and Yandex's actual analytics use case ↑ClickHouse's openness to experimental contributions and rigorous testing is impressive ↑Built-in connectors and integrations make ClickHouse a complete data warehouse solution
