Latest Patents
One of his latest patents is titled "Unified optimization of iterative analytical query processing." This invention addresses the optimization of procedures for enterprise applications by integrating both declarative query statements and imperative logic into a unified optimization technique. The input procedure can implement complex analytical queries while also incorporating iterative control flow logic, such as loops. Lee's approach allows for the enumeration of alternative query execution plans by moving queries in and out of loop boundaries through hoist and sink operations. The correctness of the program is maintained by excluding certain operations using dependency graphs. Additionally, sink subgraphs can be utilized, and query inlining is supported, leading to synergies that yield superior execution plans. By considering the computing execution resource demands of the respective alternatives, an optimal query execution plan can be developed, significantly enhancing execution performance through counterintuitive optimizations.
