A Demonstration of AQWA: Adaptive Query-Workload-Aware Partitioning of Big Spatial Data
Summary: AQWA provides adaptive, query-workload- and data-aware partitioning for distributed spatial data, incrementally refining layouts without prior workload/distribution knowledge. Demonstrated on Hadoop and Spark for range and kNN queries. (summarized by gpt-5.6-luna on Jul 24 2026)
