Abstract

The invention relates to a data copying method and device, equipment and a storage medium. The method comprises the steps of obtaining current to-be-processed target sub-data from target data corresponding to a data replication task, and writing the target sub-data into a first pipeline; reading the target sub-data from the first pipeline, obtaining first data volume information of the target sub-data, and writing the target sub-data into a second pipeline; reading the target sub-data from the second pipeline, and writing the target sub-data into a target database; and determining monitoring information of the data copying task according to the first data volume information ,concluding the data copying task when determining that the data flow state of the data copying task is abnormal according to the monitoring information, wherein the monitoring information comprises state information and progress information of data copying. According to the method, high-concurrency large-batch datareplication can be realized, and the waste of database resources can be reduced.

Description

technical field [0001] The present application relates to the field of databases, in particular to a data replication method, device, equipment and storage medium. Background technique [0002] In the current application database system environment, it is more and more common for multiple databases to coexist and use. For example, different departments in the same enterprise use corresponding databases for information application. Specifically, department A of the enterprise uses EMC's GreenPlum database, department B uses Oracle's Oracle database, and department C uses Teradata database, etc. . Based on this, due to the consideration of data backup and data synchronization, data replication between different databases has gradually become a common concern of people. [0003] In traditional technologies, a copy method is usually used to implement data replication between different databases. The copy method refers to exporting the target data in a specific format from the...
