Enzyme: Incremental View Maintenance for Data Engineering

Materialized views are a core construct in database systems, used to accelerate analytical queries and optimize batch pipelines for extract–transform–load (ETL) workflows. Maintaining view consistency as underlying data evolves is a fundamental challenge, especially in high-throughput and real-time settings. Incremental view maintenance (IVM) has been studied for decades and continues to attract significant investment from major database vendors. However, most industrial systems either offer limited SQL-operator coverage or require users to hand-tune refresh strategies.
