## AI overview

ClickHouse Cloud introduces multi-stage distributed query execution, allowing a single query to scale across many nodes by repartitioning intermediate data between stages. The approach targets bottlenecks in large joins and high-cardinality aggregations, with early TPC-H results showing up to 3.4x speedups for join-heavy queries and near-linear aggregation scaling.
