Method for ensuring data consistency under micro-service framework HTTP interaction mode

Abstract

The invention relates to the technical field of micro-service development, in particular to a method for ensuring the data consistency under a micro-service framework HTTP interaction mode. The methodincludes the steps of calling pre-operations of all auxiliary business service through a main business service, recording all the auxiliary business service in a movement manager, continuing the business if the pre-operations of all the auxiliary business service succeed or the pre-operation of a certain auxiliary business service fails, otherwise, stopping executing the execution business, if the pre-operations of all the auxiliary business service succeed, calling confirming operations of all the auxiliary business server through a collaborator, rolling back all the confirming operations and executing canceling operations of the auxiliary business service if the confirming operations fail, calling the canceling operations of all the auxiliary business service if the pre-operations of part of auxiliary business service fail till canceling succeeds. The problem that a traditional two-stage submitted protocol is poor in performance and not suitable for a micro-service framework is solved, and the three simple semantic operations on the business service can be achieved and called.

Description

technical field [0001] The invention relates to the technical field of microservice development, in particular to a method for ensuring data consistency in the HTTP interaction mode of a microservice architecture. Background technique [0002] With the promotion of microservice architecture, more and more enterprises adopt microservice architecture to build their own business platforms. While the microservice architecture brings many benefits to business development, such as single responsibility, independent development and deployment, function reuse and system fault tolerance, etc.; The dependencies among them are more complex, which makes it difficult to guarantee data consistency. At present, under the microservice architecture, the two-phase commit protocol is generally used to ensure the strong consistency of data. The two-phase commit protocol is a distributed transaction model. This model mainly uses two-phase commit to ensure the integrity of distributed transactio...

Problems solved by technology

In the case of high concurrency and involving many business modules, it will have a greater impact on the performance of the database;

[0011] 2. The microservice architecture mostly uses the HTTP protocol for communication between components. HTTP is difficult to implement for a protocol with complex semantics such as the XA protocol. Therefore, the above method is basically not applicable in the field of microservice development
