SPREE: Object prefetching for mobile computers


Mobile platforms combined with large databases promise new opportunities for mobile applications. However, mobile computing devices may experience frequent communication loss while in the field. In order to support database applications, mobile platforms are required to cache portions of the available data which can speed access over slow communication channels and mitigate communication disruptions. We present a new prefetching technique for databases in mobile environments based on program analysis. SPREE generates maps of a client program's use of structured data to be used by our prefetching runtime system. We apply SPREE in the context of mobile programming for object structured databases demonstrating an effective way to prefetch/hoard over unreliable networks with speedups up to 80% over other techniques.
