Latest Patents

One of his latest patents focuses on methods for local page writes via pre-staging buffers for resilient buffer pool extensions. This innovation involves computing systems that allow compute nodes in database systems to insert, update, and query data pages maintained in storage nodes. The process includes caching data pages locally by compute node buffer pools and providing them to buffer pool extensions on local disks as pre-copies via staging buffers. The encryption of data pages occurs at the staging buffers, enabling less restrictive update latching during the copy process. Additionally, when staging buffers are filled, data pages are written to buffer pool extensions, and metadata is updated in page tables to indicate available or valid states.

Another significant patent addresses operation fragmentation with metadata serialization in query processing pushdowns. In this method, a compute node receives a query directed to database data and generates query text fragments. Portions of metadata from the database are read from different page servers and serialized by the compute node. The page server compiles the text fragments based on the serialized metadata to generate an executable query plan, which is then executed against the data as a pushdown query operation.
