Trading Timeliness and Accuracy in Geo-Distributed Streaming Analytics

  title={Trading Timeliness and Accuracy in Geo-Distributed Streaming Analytics},
  author={Benjamin Heintz and Abhishek Chandra and Ramesh K. Sitaraman},
Many applications must ingest rapid data streams and produce analytics results in near-real-time. It is increasingly common for inputs to such applications to originate from geographically distributed sources. The typical infrastructure for processing such geo-distributed streams follows a hub-and-spoke model, where several edge servers perform partial computation before forwarding results over a wide-area network (WAN) to a central location for final processing. Due to limited WAN bandwidth… CONTINUE READING
