Title: Innovations of In-Jerng Choe in Query Processing

Introduction

In-Jerng Choe, an accomplished inventor based in Sammamish, WA, has made significant contributions to the field of query processing. With two patents to his name, Choe's work focuses on enhancing the efficiency of data handling within complex systems. Currently employed at Microsoft Technology Licensing, LLC, he collaborates with fellow inventors Boris Baryshnikov and Aleksandras Surna to push the boundaries of technology and innovation.

Latest Patents

Choe's latest patents include a groundbreaking system and method for cardinality estimation feedback loops in query processing. This innovative approach comprises various methods performed by systems and devices to optimize the performance of query hosts. The query host executes queries against data sources using an engine that relies on estimated cardinalities. As the queries are executed, query monitors generate event signals that capture actual data cardinality, runtime statistics, and query parameters. This vital event signal information is then analyzed by a feedback optimizer, which produces change recommendations for future executions of the same or similar queries. The recommendations are stored by the query host, allowing for continuous improvements in query performance.

Additionally, Choe's patent outlines a method for enforcing system resource usage limits on query requests. By grouping queries into workgroups and assigning resource pools to manage workloads, this system ensures that each query receives the necessary server resources while accommodating multiple user-submitted workloads. The differentiation among these workloads allows for specific resource limits tailored to varied user needs, thus optimizing resource allocation.
