SharkDB: An In-Memory Storage System for Massive Trajectory Data
Summary: SharkDB partitions trajectories into time-aligned frames stored as columnar in-memory blocks, enabling frame-level compression and cache-friendly processing. This frame-based in-memory column store enables parallel analytics on massive trajectories and outperforms disk/tuple-based designs for variable-length data. (summarized by gpt-5-nano on Feb 09 2026)
