Title: Innovations of Yuanzhen Ji: A Pioneer in Data Processing Technologies
Introduction
Yuanzhen Ji is a notable inventor based in Dresden, Germany, recognized for his contributions to the field of data processing technologies. With a total of five patents to his name, Ji has made significant strides in optimizing data streams and continuous queries, which are essential in today's data-driven world.
Latest Patents
One of Yuanzhen Ji's latest patents is titled "Quality-driven processing of out-of-order data streams." This patent involves systems, software, and computer-implemented methods that provide quality-driven processing of out-of-order data streams based on a configurable quality metric. The method includes identifying a configurable quality metric defined by a user or application for executing continuous queries over a sliding window. It specifies user requirements for the quality of the continuous query result. A quality threshold metric is calculated based on this configurable quality metric, which is associated with the size of an adaptation buffer for incoming tuples of the query. The method also measures a runtime quality metric associated with incoming tuples for the sliding window and modifies the adaptation buffer based on the difference between the quality threshold metric and the measured runtime quality metric.
Another significant patent by Ji is "Optimization of continuous queries in hybrid database and stream processing systems." This patent describes systems, software, and methods for optimizing continuous queries for hybrid execution over a stream processing engine and an in-memory database. The method identifies a continuous query executed at a stream processing engine, which includes a plurality of operators. An optimal plan for executing the identified continuous query is determined, and optimized placement decisions for executing each operator are made. The optimized continuous query is then executed at both the stream processing engine and the database system.
