Latest Patents

Among his latest inventions, two notable patents stand out:

1. **Adaptive Query Routing in a Replicated Database Environment**

This patent describes innovative technologies that facilitate adaptive query routing in replicated database systems. These technologies leverage various replication protocols, allowing for dynamic routing of prepared statements. When a destination replica node becomes unavailable, the system can redirect operations to source nodes or other available replica nodes. Once the originally unavailable replica node becomes available, statements can be updated accordingly for execution at the revived node. This approach also accommodates scenarios where partial data is accessible at the replica nodes.

2. **Routing SQL Statements to Elastic Compute Nodes Using Workload Class**

This invention proposes advanced methods for routing SQL statements to elastic compute nodes (ECNs) within a distributed database environment. The ECNs do not maintain persistent database tables, which distinguishes them from traditional architectures. The system identifies a workload class that matches the properties of incoming SQL statements and selects suitable elastic compute nodes for execution. This method emphasizes flexibility and efficiency, even retrieving essential data from other nodes that store persistent tables when needed.

Career Highlights

Deok Hoe Kim's career is marked by significant achievements in the tech industry, particularly in the realm of database technology.
