Latest Patents

One of Wei Yu's latest patents is titled "Query execution plans by compilation-time execution." This invention describes a query optimizer that includes a query tuner capable of performing actual execution of query fragments to obtain real results during compilation time. The optimizer uses these actual results to select the most suitable query plan. Additionally, the results may be combined with estimates for fragments that were not executed. The tree structure of the query can be traversed in either a top-down or bottom-up manner, allowing for flexible processing of nodes. A limit, such as a time or level limit, can be implemented to control the duration of the execution plan determination.

Another notable patent is "Membership self-discovery in distributed computing environments." This invention addresses the challenges of application execution in large distributed computing environments. It involves distributing application execution across multiple groups, each containing a set of host computer systems responsible for executing various operations. The membership of these groups is determined by generating configuration information based on the groups, which is then provided to the host computer systems. Each system can ascertain its membership in a particular group based on this configuration information.
