1. A computer-implemented system comprising: a logic circuit to: evaluate robustness of a selected atomic query by measuring performance of atomic query execution in a selected range of runtime conditions in a multi-dimensional parameter space, the multi-dimensional parameter space including at least one of data characteristics or an availability of a resource; produce a set of measurements to be displayed in at least one performance map, the at least one performance map indicating the measured performance in the selected range of runtime conditions; and analyze the measured performance to identify landmarks indicative of database atomic query performance degradation greater than a selected amount.
