PBench: Workload Synthesizer with Real Statistics for Cloud Analytics Benchmarking
Summary: PBench synthesizes cloud analytics workloads that replicate real execution statistics (performance metrics, operator distributions, temporal dynamics) by selecting and combining benchmark components and augmenting missing pieces. Key innovations: multi-objective optimization for component selection, progressive timestamp assignment, and LLM-based component augmentation to preserve statistical fidelity, achieving up to 6x lower approximation error vs prior work.
