Latest Patents

Nan Xing holds a patent titled "System and method for cardinality estimation feedback loops in query processing." This patent describes methods for cardinality estimation feedback loops that are performed by systems and devices. A query host executes queries against data sources via an engine based on estimated cardinalities. Query monitors generate event signals during and at the completion of execution. These event signals include indicia of actual data cardinality, runtime statistics, and query parameters in query plans. The signals are routed to analyzers of a feedback optimizer where the information is analyzed. The feedback optimizer utilizes the analysis results to generate change recommendations as feedback for later executions of the queries or similar queries performed by a query optimizer of the query host. The query host stores these change recommendations, and subsequent queries are monitored for the same or similar queries to which change recommendations are applied to query plans for execution and observance by the query monitors. Change recommendations can be viewed and selected via a user interface.
