Distance-based Outlier Query Optimization in Apache IoTDB
Summary: Addresses distance-based outlier queries in Apache IoTDB's LSM-tree where overlapping files from delayed arrivals break streaming detection. Uses per-file value buckets to derive neighbor-count bounds for overlap-aware pruning, accelerating exact outlier queries vs stream methods. (summarized by gpt-5-mini on Feb 09 2026)
