How DuckDB is USING KEY to Unlock Recursive Query Performance
Summary: Investigates USING KEY variant of recursive CTEs in DuckDB, enabling overwriting of previous intermediate results. Shows production-ready integration that reduces union-table size and runtime, validated on LDBC graphs with an interactive demo. (summarized by gpt-5-nano on Feb 09 2026)
