Abstract

The embodiment of the invention discloses a data sequence synchronization method and device, computer equipment and a storage medium. The method comprises the steps of obtaining a change record tableof a database, and sending the change record table to message middleware; distributing the messages with the same unique fields in the change record table to the same partition or the same message queue of the message middleware, the unique fields of the messages of the same data being the same; and obtaining the message from the partition or the message queue of the message middleware through a message consumer, and processing the obtained message to change the data of the database. According to the embodiment of the invention, the messages of the same data are distributed to the same partition or the same message queue of the message middleware; since the messages in the same partition or the same message queue of the message-oriented middleware are ordered, message consumers consume themessages in sequence, thereby ensuring the consistency of data synchronization.

Description

technical field [0001] The invention relates to the technical field of data processing, in particular to a data sequence synchronization method, device, computer equipment and storage medium. Background technique [0002] Data synchronization is a problem often encountered in big data, including data synchronization in SQL server. Although there are many data synchronization schemes, there are still relatively few studies on the order of data synchronization. If there is a problem with the order of data synchronization, there will be problems with data consistency. For example, for adding a data first and then modifying a data, if the order is not appropriate, it will be modified first and then added, resulting in problems with data consistency. In order to solve this problem of data inconsistency, it has become a technical problem to be solved urgently in this field . Contents of the invention [0003] Embodiments of the present invention provide a data sequence synchr...
