With a total of 3 patents to his name, Schlosser's work has had a considerable impact on how large database systems operate.
Latest Patents
One of Schlosser's latest patents is titled "Iterative multi-attribute index selection for large database systems." In this invention, the inventors have implemented a solution in a columnar in-memory database and studied access patterns of a large production enterprise system. To obtain accurate cost estimates for a configuration, they utilized the what-if capabilities of modern query optimizers. However, what-if calls are often a major bottleneck for most index selection approaches. Therefore, a key constraint is to limit the number of what-if optimizer calls. Although the inventive approach does not restrict the index candidate set, it effectively decreases the number of what-if calls. This is achieved because, in each iteration step, the number of possible index extensions is relatively small, resulting in a limited number of what-if calls.
Another significant patent by Schlosser is "Training an agent for iterative multi-attribute index selection." This invention relates to a method for training an index selection agent to iteratively determine an index set to be used when running queries against a database. The method is implemented in a computer system and is preferably based on Reinforcement Learning.
