Robust query optimization methods with respect to estimation errors: A survey
The quality of a query execution plan chosen by a Cost-Based Optimizer (CBO) depends
greatly on the estimation accuracy of input parameter values. Many research results have …

High performance stream query processing with correlation-aware partitioning
State-of-the-art optimizers produce one single optimal query plan for all stream data, in spite
of such a singleton plan typically being sub-optimal or even poor for highly correlated data …
