Problems solved by technology

In particular, for large-memory services, when server (memory) resources are limited, availability cannot be provided by deploying more copies; fault recovery time will also be extended due to memory dump after exception, service restart initialization, etc.
Usually, network service programs will improve availability by configuring client request retry, but when the retried request is still processed by the version with the same problem, it will cause fault propagation, which will reduce the number of replicas available in the system and reduce service availability

Abstract

The invention provides a multi-version program coexistence method and apparatus for a big memory service. The method comprises the steps of receiving a first request sent by a client through a server deploying a first copy, wherein the first request carries a mark of the first request processed by a program of a first version; forwarding the first request to the program of the first version for processing, and determining that the program of the first version is abnormal; sending a notice to the client, so that the client sends a second request to a server deploying a second copy, wherein the second request carries a mark of the second request processed by a program of a second version; and forwarding the second request to the program of the second version for processing by the server deploying the second copy, wherein the first version is an updated version of the second version. According to the method and apparatus, for the big memory service needing multiple versions for release or experiment, the service availability can be effectively improved without increasing the machine cost.

Description

technical field [0001] The invention relates to the technical field of the Internet, in particular to a method and device for coexistence of multi-version programs for large-memory services. Background technique [0002] On large-memory services that require high availability, the stability of multi-version programs will be affected by various factors such as hardware and software abnormalities, upgrades and changes. Hardware abnormalities, including stand-alone network card or disk failures, network switch failures, etc.; software abnormalities, including newly added code uncaught exceptions, or illegal access to memory, etc. The impact of upgrade changes, including planned downtime due to service restarts, etc. In particular, for large-memory services, when server (memory) resources are limited, availability cannot be provided by deploying more copies; fault recovery time will also be extended due to memory dump after exception, service restart initialization and other li...
