Abstract
Operations include estimating, in real time, a runtime of a query. The query optimization system receives set of query definitions for defining a target query. The system uses the set of query definition elements to determine an estimated runtime for the target query. If the estimated runtime exceeds some acceptable threshold value, then the system determines a modification to the set of query definition elements. The system uses the modification to generate a modified query, corresponding to a lower estimated runtime.
