Distributed transaction processing method based on micro service architecture

Abstract

The invention discloses a distributed transaction processing method based on a micro service architecture. The method comprises the following steps: determining a service call node and a service called node in a micro service architecture; controlling the service call node to send a service message to the service called node through a message queue, and storing the sending status of the service message; controlling the service called node to resolve the service message and executing the corresponding service according to the resolution result; controlling the service called node to feed the service execution result back to the service call node; and controlling the service call node to change the current status of the service message stored therein according to the service execution result. The service call node changes the status of own service message according to the feedback information of the service called node, and a message queue mechanism is used for saving the message status without relying on the specific development language and platform, so that the data consistency of distributed transaction is ensured, the number of network communication times between the two nodes is reduced, the communication time is short, and the system performance consumption is low.

Description

technical field [0001] The invention relates to the field of microservice architecture, in particular to a distributed transaction processing method based on the microservice architecture. Background technique [0002] In recent years, with the rapid development of cloud computing and the Internet industry, the traditional technical architecture can no longer meet the flexible growth and elastic application of business volume. In order to solve this problem, the microservice architecture came into being. [0003] In the microservice architecture, the system is split into several relatively independent business services, and each service can be deployed on a different node. When calls occur between service nodes, how to achieve transaction consistency becomes an urgent problem to be solved. At present, a two-phase commit protocol (Two-phase Commit, 2pc) method is commonly used for processing distributed transactions. That is: the client submits a request to the transaction...

Problems solved by technology

However, in the process of use, it is found that the existing two-phase commit method has the following defects: the existing method requires the transaction coordinator to actively confirm the status of each transaction executor, so it involves multiple network communications between nodes, and the communication time Long time, high system performance consumption, etc.
