Title: Yifung Lin: Innovator in Data Flow and Performance Analysis
Introduction
Yifung Lin is a prominent inventor based in Beijing, China. He has made significant contributions to the field of data flow representation and performance analysis, holding a total of 5 patents. His work primarily focuses on enhancing the efficiency of computational jobs, particularly in the context of big data.
Latest Patents
One of Yifung Lin's latest patents is titled "Generation of data flow from syntax tree." This invention introduces a computerized mechanism that formulates a data flow representation from a syntax tree, such as an abstract syntax tree (AST) generated by compiling query scripts. Each node in the syntax tree consists of tokens derived from the query script, with relationships between these tokens represented syntactically. The data flow representation can also reflect the original query script itself. To create this representation, the data types of various inputs and outputs of the syntax tree nodes are identified and bound to a corresponding data flow, while respecting dependencies between the nodes. This data flow can be visualized for authors or reviewers of the script.
Another notable patent is "Data skew finding and analysis," which addresses the challenge of reducing data skew during computational jobs, especially when responding to complex queries on large datasets. This invention involves gathering performance information for a vertex in a distributed stage, identifying performance outliers, and generating trigger instructions to collect data distribution information for evaluation of data skew.
