Sapprox: Enabling Efficient and Accurate Approximations on Sub-datasets with Distribution-aware Online Sampling
Summary: Sapprox enables efficient, accurate approximations on arbitrary sub-datasets via distribution-aware sampling. Uses a probabilistic map to flatten subsets, applies unequal-probability sampling, and optimizes unit size, yielding 20x speedups in Hadoop. (summarized by gpt-5-nano on Feb 09 2026)
