Problems solved by technology

However, in the process of real-time streaming data processing, the use of a large number of streaming data objects is not active due to long-running, and a large number of inactive streaming data objects occupy memory for a long time
[0004] Therefore, in the process of real-time streaming data processing, a large number of inactive streaming data objects occupy memory for a long time due to long-term operation, resulting in waste of system resources.

Abstract

The invention provides a streaming processing system oriented memory object management method and system. The streaming processing system oriented memory object management method comprises the following steps: detecting the state of a streaming data object in a memory; and if a detection result shows that the state of the streaming data object is an inactive state, removing the streaming data object from the memory, and moving the streaming data object to an external storage. The streaming processing system oriented memory object management method and system provided by the invention can avoid the waste of system resources since long-term operation causes a great quantity of inactive streaming data objects to occupy the memory for a long term.

Description

technical field [0001] The invention relates to the field of distributed computers, in particular to a memory object management method and system oriented to stream processing systems. Background technique [0002] With the continuous development of the Internet and the rapid rise of the Internet of Things, streaming data is widely used in application fields such as network monitoring, sensor networks, aerospace, e-commerce, smart transportation, and smart tourism. Among them, streaming data is a set of sequential, large, A sequence of data arriving in rapid succession. Compared with traditional big data, streaming data arrives continuously in massive, fast and time-varying data streams, which creates a new research problem: real-time streaming data processing. [0003] In general, real-time streaming data processing is aimed at continuously generating streaming data, quickly modeling according to application requirements, and allowing users to get feedback in real time, th...
