Smooth service upgrade method and device

Abstract

The embodiment of the invention provides a smooth service upgrade method and a smooth service upgrade device. The method comprises the steps of registering a plurality of new service nodes into a first service set, and registering the first service set into a service finding application program; executing simulative offline on a second service set including a plurality of old service nodes to be off the line from the service finding application program, connecting all new request transactions to the plurality of new service nodes, thus allowing the plurality of old service node to stop receiving the new request transaction and only process the request transactions to be processed received before simulative offline; and stopping the service of the old service nodes after the request transactions to be processed are completely processed by the old service nodes in the second service set. According to the method provided by the invention, the situation that no uncompleted request transaction exists during an upgrade process can be ensured, service jitter is avoided as much as possible, the situation that the service jitters frequently due to frequency change of the plurality of nodes during the service upgrade process is relieved, and smooth upgrade is achieved.

Description

technical field [0001] The invention relates to the technical field of service upgrading, in particular to a method and device for smooth service upgrading. Background technique [0002] The service discovery (Service Discovery) component records the information of all services in a large-scale distributed system, and people or other services can find these services accordingly. DNS is a simple example. Of course, the service discovery component of a complex system should provide more functions, such as service metadata storage, health monitoring, multiple queries and real-time updates, etc. Service discovery provides a coordination mechanism to facilitate the publishing and searching of services. The main benefit of service discovery is zero configuration: instead of using hard-coded network addresses, services can be used only by their name. [0003] The industry offers many service discovery solutions: [0004] People have been using DNS for a long time, and DNS is pr...

Problems solved by technology

[0010] The existing technical implementation principle can realize the registration and discovery of services as described above, and it can also be removed in real time when a service stops serving. In most cases, there is no problem, but if you want to upgrade a certain service When a service or gray scale test a service, the service node will change frequently. Generally, the new service node is started first, and then the old service node is shut down. In this way, there will be two service list changes inside the service discovery, which means The proxy service will need to change the configuration twice, and the proxy service will experience service jitter when making configuration changes
