Latest Patents
One of Santosh's latest patents is titled "High performance index creation." This invention describes a method for creating a high-performance index using parallel query plans with repartitioning scans and vector-based repartitioning scans. The method involves extracting index key columns from data rows of a database table to build a set of index rows. Partition boundary values are generated to divide the index rows into range-partitioned sets, which are then sorted based on the values of the index key columns. A repartitioning scan is performed on the index rows using multiple worker threads executing in parallel to build sub-indexes. The sub-indexes generated are subsequently merged to create the final index for the database table.
Another notable patent is focused on "Testing efficiency and stability of a database query engine." This invention outlines systems, methods, and computer program products for testing the stability and efficiency of a database query engine. It retains all possible query execution plans considered by a query optimizer in the form of abstract plans. Each abstract plan is tested for stack traces and incorrect results during query execution. The invention also includes determining an optimizer efficiency index by comparing each abstract plan with the chosen query execution plan and classifying them based on performance.
