Abstract

The embodiment of the invention is suitable for the technical field of data processing, and provides a data synchronization method and device and terminal equipment, and the method comprises the steps: building a data link between a source database and a target database through employing a preset OGG tool; generating a plurality of data transmission channels between a source database and a targetdatabase based on the data link; when an operation behavior for any data in a source database is detected, analyzing the operation behavior into a byte stream, wherein the byte stream carries time information of the operation behavior; and transmitting the byte stream to a target database through a plurality of data transmission channels, wherein the target database is used for compiling the bytestream into an operation behavior and replaying the operation behavior in the target database based on the time information so as to realize data synchronization. According to the embodiment, the problems that during data consistency processing of a big database, influences of computer resources are large, and timeliness is low are solved.

Description

technical field [0001] The invention belongs to the technical field of data processing, and in particular relates to a data synchronization method, a data synchronization device, a terminal device and a computer-readable storage medium. Background technique [0002] In the field of distributed storage, in order to increase the high availability of the system, multiple copies of the same data are often stored. But this approach also brings the problem of data consistency. Data consistency means that the result of transaction execution must be to change the database from one consistent state to another. Guaranteeing data consistency enables all data to have a consistent state when a transaction completes. [0003] In the prior art, data consistency processing in the field of big data is mostly implemented in a synchronous manner of batch processing and multi-thread fetching. For example, for a sqoop (a batch data migration tool) process, it can be divided into multiple thre...
