Embodiment Construction

[0046] See shown in 1, basic flow process of the present invention is:

[0047] Step 1: The upstream application sends a message to be confirmed to the reliable message system, if the reliable message system receives the message, go to step 2, otherwise go to step 6;

[0048] Step 2: The reliable message system saves the message to be confirmed and returns it. If the upstream application receives the confirmation message, go to step 3; otherwise, go to step 6;

[0049] Step 3: The upstream application executes the local business. If the execution is successful, proceed to step 4; otherwise, roll back the local transaction and proceed to step 6;

[0050] Step 4: The upstream application notifies the reliable message system to confirm that the business has been executed and sends a message. If the reliable message system receives the message, perform step 5. Otherwise, the reliable message system queries the upstream application for the status of the confirmation message. If the...

Abstract

The invention relates to the technical field of micro-service development, in particular to a method for guaranteeing the data final consistency through a system based on a micro-service framework. Through the combination of a method using a message queue and the determination and retransmission mechanism of messages, final consistency can be achieved after automatic or manual compensation; modules related to the final data consistency include an upstream application for executing service and sending MQ messages, a reliable message service and message assembly for coordinating with the transmission of downstream messages and ensuring the consistency of upstream data and downstream data, and a downstream application for monitoring the MQ messages and executing service. The problems that traditional two-stage protocol submitting performance is poor and a processing chain is long are solved.

Description

technical field [0001] The present invention relates to the technical field of microservice development, in particular to a method for ensuring the final consistency of data in a system based on 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; thus making 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 tr...
