Problems solved by technology

[0003] In the existing technology, the stream computing platform usually does not have the ability to optimize the operator code of the stream application. After the application is deployed to the stream computing platform, if the developer does not actively update the operator code of the stream application, the operator code of the stream application will basically remain the same, and the performance of streaming applications cannot be improved any more

Abstract

The invention discloses a stream application optimization method. The method comprises the steps of obtaining an application stream graph and an initial operator code of a to-be-optimized stream application, wherein the application stream graph comprises an operator, and the initial operator code is used for describing initial operation logic born by the operator; determining a data stream graph of the operator according to the initial operator code; determining a hotspot path in a plurality of paths of the data stream graph according to the data stream graph of the operator and the initial operation logic born by the operator, wherein each of the paths represents arithmetic logic, and the hotspot path is arithmetic logic of which a usage frequency meets a preset condition in the arithmetic operation process; and optimizing a local operator code corresponding to the hotspot path so as to obtain an optimized operator code. According to the stream application optimization method provided by an embodiment of the invention, the operator code can be automatically optimized, so that the usability and computing performance of the stream application are improved.

Description

technical field [0001] The invention relates to the field of computer technology, in particular to a stream application optimization method and device. Background technique [0002] Stream processing is implemented by deploying stream applications on the stream computing platform. Stream application developers write the operator code of the stream application in the stream language, and construct the application flow graph of the application based on the operator code. The stream processing of this application is realized by operator code and application flow graph. The application flow graph includes operators and data flows. Operators are logical processing units that carry services, and data flows are data interacted between operators. Application flow graphs are used to describe the data processing and interaction process of stream applications. The operator code is used to describe the logic carried by the operator in the application flow graph. The quality of the ope...
