Description
In the recent project of China Spallation Neutron Source (CSNS), a new designed distributed stream-processing framework is applied as the fundamental schema of data process system on user cooperative instruments. It is constructed with the open-source Apache Kafka software, which aims to aggregate the big data for manipulate sharing, and also with an synchronous trigger&tagging system, which provide synchronous mark for verious data sources. Correlation could be identified among different measurements and subsystems to perform asynchronous manipulation，while quasi real-time characteristics is another profit from the stream-processing framework. Efficiency and adaptability of this technical framework has been verified during the operation of constructed user cooperative instruments in CSNS. An increasing number of data-processing functions and experiment methods have got benefit from it.
