Evidence-backed facts

  1. ClickHouse is documented as a column-oriented SQL DBMS for OLAP, available as open-source software and a cloud offering. informative
  2. Analytical queries can filter and aggregate selected columns, and supported SQL behavior must be checked against the exact query and deployment. informative
  3. Replication is asynchronous and role-based access control is separately configured; a write acknowledgement is not universal proof that every replica is current. informative
  4. Some calculations and sampled queries can be approximate, so an answer must declare exactness instead of treating every result as exact or transactional. informative
