Spatial Joins in Main Memory: Implementation Matters!
Summary: Main-memory spatial joins reveal that implementation choices trump high-level algorithms. Re-implementing the worst technique (Simple Grid) with small changes yields a multi-fold speedup, overturning prior results and underscoring fragility of memory-resident empirical conclusions.
