With a total of 2 patents, Kossmann's work focuses on improving the efficiency of database queries through innovative methods.
Latest Patents
Kossmann's latest patents include "Iterative multi-attribute index selection for large database systems" and "Training an agent for iterative multi-attribute index selection." In the first patent, he and his team implemented a solution in a columnar in-memory database, studying access patterns of a large production enterprise system. They aimed to obtain accurate cost estimates for configurations by utilizing the what-if capabilities of modern query optimizers. A key challenge addressed in this patent is the limitation of what-if optimizer calls, which are often a bottleneck in index selection approaches. The inventive method reduces the number of what-if calls by ensuring that the number of possible index extensions remains manageable in each iteration.
In his second patent, Kossmann focuses on training an index selection agent using Reinforcement Learning. This method is designed to iteratively determine an optimal index set to be used when executing queries against a database. The implementation of this method in a computer system showcases Kossmann's commitment to advancing database technology.
