Latest Patents

One of Prashant's latest patents focuses on heuristic database querying with dynamic partitioning. This invention implements dynamic partitioning of a search space of queries for flexible, heuristic database querying. The process involves dividing the search space for a submitted query into smaller parts by augmenting the queries with an additional predicate that includes a dynamic partition key and selected values based on heuristics, such as recency and relevancy. A variety of candidate augmentations of the query and corresponding query plans are generated and evaluated based on additional heuristics to determine the best execution for optimal result quality and latency. The selected query plan is executed to retrieve results that satisfy the query, utilizing pagination for effective presentation. This procedure of generating candidate query plans, selecting one for execution, and paginating results is repeated until a search termination criterion is met.
