Ghost: A General Framework for High-Performance Online Similarity Queries over Distributed Trajectory Streams
Summary: Ghost is a distributed framework for online trajectory similarity search and join over real-time streams, with IOSC making pairwise distance linear in trajectory length. Histogram indexes with pruning bounds support streaming similarity on Flink via CostPartitioner, achieving 6-20x throughput and memory savings. (summarized by gpt-5-nano on Feb 09 2026)
