Distance-based Outlier Query Optimization in Apache IoTDB
Summary: Optimizes distance-based outlier queries in IoTDB’s LSM-tree storage, where late arrivals create overlapping files. Bucket statistics derive neighbor-count bounds across buckets/files, enabling pruning under varied distance, count, window, and slide parameters. (summarized by gpt-5.6-luna on Jul 24 2026)
