Sprint: Speculative Prefetching of Remote Data
Remote data access latency is a significant performance bottleneck in many modern programs that use remote databases and web services. The authors present Sprint - a run-time system for optimizing such programs by prefetching and caching data from remote sources in parallel to the execution of the original program. Sprint separates the concerns of exposing potentially-independent data accesses from the mechanism for executing them efficiently in parallel or in a batch. In contrast to prior work, Sprint can efficiently prefetch data in the presence of irregular or input-dependent access patterns, while preserving the semantics of the original program.
