GRAPH TYPE – Schema enforcement made easy (Preview)
Blog post from Neo4j
Neo4j introduces GRAPH TYPE as a preview feature in version 2026.02, designed to simplify schema enforcement by allowing a holistic declaration of the data model instead of managing numerous isolated constraints. This new feature enables users to define nodes, multi-label implications, and relationship connections in a single, coherent structure, enhancing data integrity and maintainability while maintaining the flexibility of the graph database. GRAPH TYPE supports commands like SET, ADD, ALTER, and DROP to manage the lifecycle of the enforced data model, providing advanced validation capabilities that ensure strict adherence to specified data connections and label requirements. The preview is available across various editions of Neo4j, including Enterprise and Aura, and encourages user feedback to refine its functionality before general availability.
