Inside the dbt Fusion engine: A full rewrite in Rust to unlock value for data teams

"The dbt Fusion engine is a full rewrite of dbt Core in Rust. It's a milestone for dbt because it sets a new foundation for us to build all future products. This unlocks an enormous potential." — Elias DeFaria, Manager of Product Management at dbt Labs Elias breaks down what makes dbt Fusion revolutionary and why it's the foundation for the future of analytics engineering. What makes dbt Fusion transformational: ✅ Complete engine rewrite in Rust with SDF Labs technology ✅ Real-time feedback as you type—no warehouse validation needed ✅ Native SQL syntax and semantics understanding ✅ Column-level lineage injected into developer experience ✅ State-aware execution that remembers previous runs ✅ Skip models that don't depend on new data ✅ 40-50%+ cost savings on dbt projects ✅ Available to dbt Core community users—deploy just like Core "Fusion is a compiler that understands SQL natively. With dbt Core, you have to run code against the warehouse to determine if it's valid. With Fusion, we're able to determine when code is invalid as you type it with real-time feedback." "State-awareness might be the most impactful aspect of the new engine. We can understand data freshness and skip models that don't depend on new data. We're seeing it drive cost savings north of 40-50% on some dbt projects." For the dbt Core community: "Fusion can be deployed just like Core and all the enhancements around developer experience and faster runtimes are available to you. You don't have to talk to us—you can deploy it just like Core with no relationship with dbt Labs." Experience the next generation of dbt.
