Document Type and Number:
WIPO Patent Application WO/2018/129787
Kind Code:
A1
Abstract:
The present invention relates to the technical field of data storage. Disclosed in the present invention are a data persistence method and system in stream computing. The method comprises: a management module initiates a task; extract, according to the task, a key corresponding to the task from a data source; extract, according to the key, a value corresponding to the key from the data source, and perform data processing to generate intermediate data and a first signal, and store the intermediate data and the first signal; and detect whether the first signal is stored, and send detection information to the management module. By using the present invention, results of intermediate data persistence can be effectively fed back to ensure that intermediate data persistence is transactional.
