DITA: Distributed In-Memory Trajectory Analytics

Summary: DITA is a distributed in-memory trajectory analytics system addressing data-locality partitioning and load balancing with Spark SQL APIs. Key ideas: trie pivot indexing with global/local indexes; a bi-graph cost model and graph-based distributed joins. (summarized by gpt-5-nano on Feb 09 2026)
