Latest Patents

Cheng’s listed patents, both titled “Techniques for Deterministically Routing Database Requests to Database Servers,” describe methods for coordinating database engines, servers, and files.

One patent describes a database server that concurrently runs multiple database engines. When an I/O request arrives, the server selects an available engine, makes the relevant database file accessible, and directs the engine to perform the requested operation.

The other patent addresses access to database files shared among multiple users. A database server identifies the storage server that provides access to a file and obtains an exclusive lock. Once the lock is secured, the server records associated information in the file’s metadata and performs the I/O operation.
