Coordination method and device for data consistency under cloud environment distributed transaction and medium

Abstract

The invention discloses a coordination method and device for data consistency under distributed transactions in a cloud environment and a medium. The method comprises the following steps of splittingthe local transaction request into a plurality of operation requests, calling individual target databases, controlling the target database to enter a temporary state under the condition that the calling is successful or keeping the original state under the condition that the calling is failed; and receiving state return information from the target databases, respectively sending a service operation instruction to each target database when the state return information sent by each target database is used for representing the temporary state, and otherwise, carrying out rollback so as to enableeach target database to generate consistent response result data for the local transaction request. The device comprises a local transaction splitting module, a target data calling module, a return information receiving module and a data consistency control module. According to the method, it can be guaranteed that completely different databases provide consistent response results under the micro-service architecture, and particularly, final consistency of data is guaranteed under the abnormal condition.

Description

technical field [0001] The present invention relates to the technical field of cloud computing, and more specifically, the present invention relates to a method, device, and medium for coordinating data consistency under distributed transactions in a cloud environment. Background technique [0002] With the rise of cloud computing technology, functions such as online payment and account registration are becoming more and more convenient. At present, microservices in the distributed software environment of the cloud environment are becoming more and more detailed. In order to meet more service requirements, a single system (such as a group of servers in a certain location) is often split into multiple services. , each service is implemented through its own database. In a microservice scenario, a transaction request often needs to span multiple completely different databases, which makes the process of accessing data in the database complicated. It is difficult for existing t...
