Sub-millisecond Stateful Stream Querying over Fast-evolving Linked Data
Yunhao Zhang, Rong Chen, Haibo Chen · 2017
Applications like social networking, urban monitoring and market feed processing require stateful stream query: a query consults not only streaming data but also stored data to extract timely information; useful information from streaming data also needs to be continuously and consistently integrated into stored data to serve inflight and future queries. However, prior streaming systems either focus on stream computation, or are not stateful, or cannot provide low latency and high throughput to handle the fast-evolving linked data and increasing concurrency of queries.
