PGShield: Maintaining Path Constraints in Property Graphs
Summary: PGShield is the first system to enforce arbitrarily long, complex path constraints in property graphs before updates commit, avoiding post hoc detection and repair. It extends GQL with constraint-aware updates and uses graph metadata as a novel index for efficient verification and user feedback. (summarized by gpt-5.6-luna on Aug 28 2026)
