Flux capacitors for JavaScript deloreans: approximate caching for physics-based data interaction
summary
Flux Capacitor is a JavaScript middleware that adds a client-side R-tree cache and motion analyzer to prefetch and approximate backend results for UI widgets. Interaction-rate–aware prefetching adapts prefetch size to instantaneous query speed and cuts stall count and stall time roughly in half versus fixed-range prefetching; physics-aware prefetching generates the whole inertial query trace at action start and yields the best latency with most queries under 100 ms and overall interaction time reduced. Experiments use UCI 3D Road Network traces and web slider/map traces.
