Title: Junfeng Liu and LSM-Tree Database Innovation.
Introduction
Junfeng Liu is an inventor associated with Nanyang Technological University in Singapore. His patent work addresses the configuration of Log-Structured Merge (LSM) trees, a data structure used in key-value databases.
Latest Patents
Liu is credited with 1 patent: “Method and System for Configuring a Log-Structured Merge (LSM)-Tree Structure for a Key-Value Database.” The invention determines capacity parameters for intermediate levels of an LSM-tree based on an optimal tradeoff between range-lookup costs and update costs. It then configures the tree using those parameters. The patent also describes a corresponding configuration system and an LSM-tree-based key-value database system.
Career Highlights
Liu’s documented patent contribution focuses on database architecture and the performance of key-value storage systems. The disclosed method aims to balance the costs of two important operations: range lookups and updates.
Collaborations
The patent lists Siqiang Luo and Fan Wang as Liu’s coworkers. Their shared work concerns configuring LSM-tree structures for key-value databases.
Conclusion
Junfeng Liu’s patent highlights an approach to tuning LSM-tree capacity levels to balance lookup and update performance in key-value databases.
