Latest Patents

Among his latest patents, one notable invention is titled "Query hints for caching and replication." This method involves receiving a query for data from a database server, which includes an indication of a maximum lag. The invention determines whether a hint is available to apply to the query, affecting its execution. If no hint is available, a baseline database server is selected. Conversely, if a hint is available, a replication server or cache server is chosen based on the hint and the maximum lag, allowing for efficient query processing.

Another significant patent is "Cached views," which relates to view caching techniques. This invention caches some intermediate results of previous query executions for a limited time to avoid costly re-computation. It utilizes a cache manager to assess whether a subsequent user request can be satisfied by an existing cache instance or if a new cache instance is necessary. The design includes defining cache columns and creating cache instances for each tuple of literals, optimizing memory usage through enhanced reuse and eviction policies.
