Latest Patents

Junyi Xie's latest patents focus on methods and apparatus for shared expression evaluation across relational database management systems (RDBMS) and storage layers. The first patent describes techniques for sharing expression evaluation across a database management system and a storage layer. In this embodiment, a computer identifies a plurality of target operators that includes an expression computing a common value. The storage layer evaluates this expression during a table scan of stored data. For at least one target operator, the computer modifies the row input to add a column for the evaluation result, which comprises the common value from the storage layer. The query execution plan is then performed by both the database management system and the storage layer.

The second patent also addresses shared expression evaluation across RDBMS and storage layers. It identifies a plurality of target operators that include a common expression. Each target operator corresponds to a step that evaluates this common expression during query execution. The target operators are modified to enable sharing of the evaluation result. During query execution, the evaluation result is shared among the target operators. In other embodiments, the evaluation of the common expression is pushed to a storage layer, allowing the database management system to retrieve the evaluation result from the storage layer during query execution.
