SpatialSPE

Overview

• SpatialSPE accepts a continuous query and QoS budgets (expressed as latency and accuracy targets) and employs our spatial-aware sampling method (that we dub as SAOS, which is an integral part of SpatialSPE) to select an appropriate sample,
• then it computes an approximate answer and serves it to the user incrementally, together with rigorous error bounds.
• We have implemented SpatialSPE on top of Spark Structured Streaming
