Title: Rithvik Chandan and Scalable Database Query Execution.

Introduction

Rithvik Chandan is an inventor based in San Francisco, California. His patent work addresses scalable execution of database queries that limit the number of rows returned across multiple partition levels.

Latest Patents

Chandan is associated with one patent: “Multi-stage parallelization model for scalable execution of partitioned row limiting.” The invention describes a database command that specifies an ordering key, a hierarchy of partition keys, limits on the number of partitions at each level, and a row limit for each partition-key combination.

The method coordinates worker processes and a query coordinator to perform initial sorting of partition keys. It then distributes results so that rows with unique partition-key combinations remain on individual workers, allowing those workers to complete the remaining sorts locally while avoiding duplicate rows.

Career Highlights

Chandan’s listed patent is assigned to Oracle International Corporation. Its subject matter focuses on parallel processing and partition-aware sorting to support scalable database query execution.

Collaborations

Chandan’s listed coworker is Srikanth Bellamkonda. The available information identifies their professional association but does not specify their respective contributions to the patent.

Conclusion

Rithvik Chandan’s patent describes a coordinated, multi-stage approach to partitioned row limiting that distributes sorting work across database workers while preventing duplicate results.
