SH2O: Efficient Data Access for Work-Sharing Databases
Summary: SH2O replaces shared filters with multidimensional range access patterns to reduce bottlenecks in highly concurrent work-sharing databases. Three-tier design: spatial indices, a range-optimizer, and partitioned, independent access with tuning—yields 1.8–22.2× speedups on hundreds of queries.
