GRainDB: A Relational-core Graph-Relational DBMS
Summary: GRainDB extends DuckDB into a relational-core graph-relational DBMS, adding graph modeling, querying, and visualization while staying within the RDBMS engine. It augments internals with pointer-based joins on system RIDs and adjacency-list-like RID indices to accelerate graph workloads. (summarized by gpt-5-mini on Feb 09 2026)
