τ-Synopses: A System for Run-Time Management of Remote Synopses

摘要

τ-Synopses is a system designed to provide a run-time environment for remote execution of various synopses. It enables easy registration of new synopses from remote platforms, after which the system can manage these synopses, including triggering their construction, rebuild and update, and invoking them for approximate query processing. The system captures and analyzes query workloads, enabling its registered synopses to significantly boost their effectiveness (efficiency, accuracy, confidence), by exploiting workload information for synopses construction and update. The system can also serve as a research platform for experimental evaluation and comparison of different synopses.
