Chimera: A system design of dual storage and traversal-join unified query processing for SQL/PGQ
Summary: Chimera combines PostgreSQL’s relational store with a topology-aware graph store, treating graph structure as first-class rather than a materialized view. Its unified Traversal-Join plans interleave graph traversal and relational joins for scalable, high-throughput SQL/PGQ. (summarized by gpt-5.6-luna on Jul 24 2026)
