## Проекции {#projections}

Проекции похожи на [материализованные представления](../../../sql-reference/statements/create/view.md#materialized), но определяются на уровне кусков данных. Это обеспечивает гарантии согласованности данных наряду с автоматическим использованием в запросах.
|
||||
|
||||
Проекции — это экспериментальная возможность. Чтобы включить поддержку проекций, установите настройку [allow_experimental_projection_optimization](../../../operations/settings/settings.md#allow-experimental-projection-optimization) в значение `1`. См. также настройку [force_optimize_projection ](../../../operations/settings/settings.md#force-optimize-projection).
