Abstract
This disclosure describes a workload reduction system that reduces the complexity of workloads sent to a database system. For instance, the workload reduction system pre-processes workloads sent to a database system by generating reduced workloads that include less complex queries that reference fewer tables or columns than the original workloads. In various implementations, the workload reduction system uses table reduction functions and query re-writing functions to generate the reduced workloads. As a result, the workload reduction system improves computational efficiency by rewriting complex queries from workloads into simpler ones that speed up index tuning and decrease individual what-if call times.
