Latest Patents

One of his latest patents is titled "High availability and automated recovery in scale-out distributed database system." This invention introduces acceleration techniques for resuming offloaded execution by replacing a failed computer with a hot spare computer. In this system, a distributed database management system (DBMS) configures a set of participating computers and spare computers. When a participating computer fails, the DBMS can seamlessly send the same offload query plan to a replacement computer, ensuring continued successful execution despite the failure.

Another significant patent is "Server-side extension of client-side caches." This invention involves techniques that allow a storage server computer to manage data blocks efficiently. Upon receiving an eviction notification from a database server, the storage server retrieves the evicted data block from its persistent cache and stores it in its volatile cache. This process ensures that when the database server requests the data block, it can be quickly retrieved and sent back, maintaining optimal performance.
