UlTraMan: A Unified Platform for Big Trajectory Data Management and Analytics

Summary: UlTraMan provides a platform for trajectory data management and analytics, avoiding heterogeneous systems. It extends Spark with a built-in key-value store and reworks MapReduce for random access, enabling retrieval, aggregation, and pattern mining. (summarized by gpt-5-nano on Feb 09 2026)
