Abstract

The invention discloses a distributed transaction data synchronization method, which comprises the following steps of: after detecting that a distributed transaction starts, analyzing a distributed transaction event in an upstream first distributed database log according to a log writing rule of the distributed transaction, extracting specified information in the distributed transaction event and performing structured processing to generate a structured variable; and storing the structured variable to support subsequent synchronization operations such as data filtering, routing and grammar conversion, and performing data change unified operation on the structured variable after receiving a submission or rollback notification. According to the method, the distributed transaction data change of a data source is stored, and whether the distributed transaction data change is sent to the downstream or not is judged according to a data source distributed transaction control statement, so that the atomicity problem of writing of a data change target end in the same distributed transaction during distributed transaction data synchronization is solved. The invention further discloses a distributed transaction data synchronization device and equipment and a readable storage medium, which have corresponding technical effects.

Description

technical field [0001] The present invention relates to the technical field of data processing, and in particular, to a distributed transaction data synchronization method, apparatus, device and readable storage medium. Background technique [0002] Data transmission and migration is one of the infrastructure solutions used by medium and large-scale enterprises to solve common data problems. Specific usage scenarios include: collocation with big data computing services to achieve low-cost massive data computing and analysis, non-stop data migration, and data mining. scattered and so on. [0003] At present, the open source community and cloud vendors provide a variety of data synchronization and migration services. For the medium and large-scale mutual gold industry, due to the characteristics of strong data consistency, low latency, and large data volume, the core business is widely used and distributed. transactional database. Due to business requirements, the online bus...
