Data synchronization method and device, electronic equipment, system and storage medium

The embodiment of the invention provides a data synchronization method and device, electronic equipment, a system and a storage medium, and the method comprises the steps: calling a big data synchronization tool to obtain full-amount user information corresponding to a video application from a first database, and obtaining a full-amount video record from a second database, and obtaining a video record corresponding to the full-amount user information from the full-amount video record, and storing the video record corresponding to the full-amount user information in a third database so as to be read by different services. According to the embodiment, all user information and video records can be obtained at a time by calling the big data synchronization tool, and the video records corresponding to all user information are screened out and then synchronized to the third database, so that rapid updating of data in the third database is realized, time is saved, and calling of different services is facilitated. 本发
