ClickHouse supports two types of materialized views. Incremental (continuous) materialized views act as insert triggers: when data is inserted into a source table, the view's SELECT query runs on the newly inserted block and writes the result to a target table. This provides near real-time transformation with no manual scheduling. Refreshable materialized views take a different approach, rebuilding their entire result set on a schedule (e.g., REFRESH EVERY 1 HOUR). They support DEPENDS ON for chaining views, can execute complex multi-table queries, and do not add per-insert overhead. Choose incremental views when you need real-time results; choose refreshable views when periodic updates are acceptable and you want to avoid insert-time overhead.
