Abstract
Optimization of procedures for enterprise applications can take both declarative query statements and imperative logic into account in a unified optimization technique. An input procedure can implement complex analytical queries and also include iterative control flow logic such as loops. Alternative query execution plans for the procedure can be enumerated by moving queries out of and into loop boundaries via hoist and sink operations. Program correctness can be preserved via excluding some operations via dependency graphs. Sink subgraphs can also be used. Query inlining can also be supported, resulting in synergies that produce superior execution plans. The computing execution resource demand of the respective alternatives can be considered to arrive at an optimal query execution plan that can then be used to actually implement execution of the procedure. Execution performance can thus be greatly improved by performing counterintuitive optimizations.
