Index-Based Join Size Estimation Using Adaptive Sampling
SIGMOD '21: Proceedings of the 2021 International Conference on Management of DataJune 2021, Pages 2932–2933https://doi.org/10.1145/3448016.3450572Cost-based query optimizers rely on cardinality estimates of intermediate results to avoid suboptimal query execution plans. However, when confronted with ad-hoc queries on big data, said optimizers can produce large estimation errors, resulting in ...
