In-Database Time Series Clustering
Summary: Proposes in-database K-Shape for time-series clustering across ranges, mitigating LSM-tree reordering and avoiding per-query full data loading. Introduces Medoid-Shape and its in-database variant for long series, with Apache IoTDB implementation and experiments showing higher efficiency with comparable accuracy.
