Abstract

The invention provides a stream application updating method, a master control node and a stream computing system. The method includes: acquiring a logical model of a stream application after updating, and comparing the updated logic model and an initial logic model to determine a to-be-adjusted stream; generating an updating instruction according to the to-be-adjusted stream; issuing the generated updating instruction to a working node to allow the working node to adjust streams among PE distributed on the working node according to the updating instruction. By the method, online updating of the stream application can be achieved without interrupting services.

Description

technical field [0001] The invention relates to the field of computer technology, in particular to a stream application upgrading method, a master control node and a stream computing system. Background technique [0002] With the advent of the era of big data, the market demand for real-time processing, analysis, and decision-making of massive data continues to expand, such as: accurate advertising push in the telecommunications field, real-time analysis of transaction dynamics in the financial field, real-time monitoring in the industrial field, etc. In this context, data-intensive applications, such as financial services, network monitoring, and telecom data management, have been more and more widely used, and stream computing systems suitable for data-intensive applications have also emerged as the times require. The data generated by data-intensive applications has the characteristics of large data volume, fast speed, and time-varying. When a data-intensive application i...
