Abstract

The embodiment of the invention discloses a data downloading method, device and system, a terminal and a storage medium. The method comprises the steps of obtaining a data downloading task; sending the data downloading task to a data service cluster, so that the data service cluster obtains target data from the source data table according to the data downloading task and creates a target data table according to the target data; and downloading the target data table from the intermediate storage device, wherein the target data table is sent to the intermediate storage device by the data service cluster. Namely, in the embodiment of the invention, the data service cluster sends the created target data table to the intermediate storage device, so that the terminal can download the target data table from the intermediate storage device at any time, and the problem that the storage time is relatively short due to the fact that the target data table is in a cache state is solved; according to the method, the requirement of the user for obtaining the target data table or part of the target data again after a long time is met, and a more convenient, economical and efficient data downloading mode is provided for the user.

Description

technical field [0001] Embodiments of the present invention relate to computer technologies, and in particular, to a data downloading method, device, terminal, system, and storage medium. Background technique [0002] In the traditional data download solution, the user's local client must be online. However, due to many factors affecting the download process (such as large data files and slow network speed), the process of downloading data takes a long time, so there are more and more solutions for downloading data offline. [0003] In the existing offline data download solution, the user sends a data download request to the server, the server detects whether the corresponding data is in the cache, and if the data is in the cache, the user is informed, and the user directly obtains the entire data file from the cache; if not, the server The data download request is forwarded to the task scheduler, and the task scheduler downloads; the task scheduler adds the data to the cac...
