Problems solved by technology

Although these solutions guarantee the availability of the software during the update process, due to the uncertainty of the update timing, it may cause the runtime distributed transaction to call different versions of the target update service, thereby destroying the security of dynamic update, that is, consistency. sexual demands

Abstract

The invention discloses a micro-service dynamic updating method supporting transaction consistency, which belongs to the technical field of software maintenance and comprises the following contents: insertion of a flow agent and a dynamic updating process supporting transaction consistency are conducted, wherein a mode of inserting the flow agent is adopted to take over a user request, intercept and extract distributed transaction information in the user request, add a corresponding distributed transaction identifier and manage the distributed transaction identifier; a dynamic updating process supporting transaction consistency describes how to go from a new version to revoke an old version, and the continuous availability of the system is ensured while the target service is dynamically updated. Compared with a common deployment scheme, in the aspect of micro-service dynamic updating, the method achieves better balance in the aspects of timeliness and interference while meeting the consistency requirement, can be applied to different micro-service systems, and has higher application values.

Description

technical field [0001] The invention relates to a microservice dynamic update method supporting transaction consistency, belonging to the technical field of software maintenance. Background technique [0002] As the scale of software systems expands, system maintenance and evolution become more and more complex. Traditional applications package all functionality into a single unit called a monolith. The monolithic application architecture is simple and easy to deploy, but it is not flexible enough to guarantee the rapid and continuous delivery of software applications, so the microservice architecture came into being. [0003] As a new technology for deploying applications and services in the cloud, microservice architecture has become the latest popular architecture. The microservice architecture divides complex software applications into several smaller services, each of which can be independently deployed, upgraded, extended, and replaced. The microservices in the whol...
