Data storage method and device, equipment and storage medium

The invention discloses a data storage method and device, equipment and a storage medium. The invention relates to the technical field of big data/data analysis and mining. The method comprises the following steps: acquiring service data and pre-configured demand parameters; determining demand data according to the demand parameters and the business data; and generating data fragments according to the timestamp information of the demand data, and storing the data fragments. According to the scheme, all business data does not need to be stored, and the storage cost is reduced. Besides, the stored data is the demand data generated based on the demand parameters and the business data instead of the business data, which is equivalent to preposing the post-processing operation of the business data, so that the post-processing of the business data is avoided when the demand data is needed subsequently, and the subsequent data operation amount of the business data is reduced. 本发明公开了一种数据存储方法、装置、设备和存储介质。本发明涉及大数据/数据分析与
