Join-Aware Materialized Views Close the Rewrite Gap for Star-Schema BI
The article explains how join‑aware materialized views retain fact‑to‑dimension joins, enabling automatic query rewrite for common star‑schema dashboards. By contrast, single‑table MVs miss grouping attributes and cannot accelerate such queries. It surveys support across major warehouses (StarRocks, BigQuery, Redshift, Oracle) and the underlying optimizer complexity.
