The invention relates to the field of big data, and discloses a data synchronization method and device for double machine rooms, equipment and a storage medium, which are used for preventing the problem of data loss and also used for improving the synchronization efficiency of data synchronization. The data synchronization method of the double machine rooms comprises the following steps: receiving a full-quantity synchronization instruction, and judging whether the full-quantity synchronization instruction is started to be executed or not; if the full-amount synchronization instruction is started to be executed, reading a directory information set from a distributed application program coordination service cluster of the first machine room, and generating target full-amount data according to the directory information set and preset full-amount data; synchronizing the target total data to a second machine room; receiving an incremental synchronization instruction, and judging whether to start executing the incremental synchronization instruction based on the incremental synchronization instruction; if the incremental synchronization instruction is started to be executed, reading the historical synchronization offset to perform data filtering, and generating target incremental data; and synchronizing the target incremental data to the second machine room. In addition, the invention also relates to a block chain technology, and the full-amount synchronization instruction can be stored in a block chain.
Description
technical field [0001] The present invention relates to the technical field of data processing, in particular to a data synchronization method, device, equipment and storage medium for two computer rooms. Background technique [0002] Zookeeper is an open source distributed coordination service. Distributed applications can implement functions such as data publishing / subscribing, naming services, distributed coordination / notification, cluster management, configuration maintenance, and distributed locks based on zookeeper. At present, in order to avoid network failures, fires in a single computer room, or even large irresistible disasters such as earthquakes and floods in the entire city, to ensure that the system can continue to run without interruption, the application needs to be deployed in at least two computer rooms, and then zookeeper needs to be implemented in the two computer rooms. Data synchronization to ensure the consistency of other application data. [0003] I...
