On the Relative Cost of Sampling for Join Selectivity Estimation

Summary: Quantifies when sampling (t_cross) is cheaper than computing the exact star-join for selectivity estimation, deriving bounds and approximations for relative cost as functions of input relation sizes, arity, and the estimator's precision criterion. Identifies dangling tuples as a major negative factor and characterizes mixed effects of data skew, yielding concrete regimes and thresholds that indicate when sampling is or isn't cost-effective for join selectivity estimation.
