Selective Late Materialization in Modern Analytical Databases
Summary: Recasts late materialization for vectorized column stores as Selective Late Materialization (SLM), choosing each attribute’s materialization point independently per query. DuckDB integration improves JOB performance 14.7% over early and 8.9% over late materialization, reaching 76.7% per-query latency reduction. (summarized by gpt-5.6-luna on Jul 24 2026)
