Latest Patents

Chengyang Zhang holds a patent titled "Incremental simplification and optimization of complex queries using dynamic result feedback." This patent outlines techniques for improving complex database queries by determining whether to adopt a static or dynamic query execution plan based on specific metrics. When a dynamic query execution plan is chosen, the database query is divided into fragments, and a plan fragment is generated for each. The execution of these fragments provides feedback that initiates query rewrite rules, ultimately simplifying the corresponding query fragments. The rewritten fragments are then combined to create a dynamic query plan.
