SSTD: A Distributed System on Streaming Spatio-Textual Data
Summary: SSTD is a distributed in-memory engine for continuous and snapshot spatio-textual stream queries with spatial, textual, and temporal predicates. Its QT (Quad-Text) tree jointly partitions query/data workloads, while adaptive rebalancing maintains throughput and robustness under distribution shifts. (summarized by gpt-5.6-luna on Jul 24 2026)
