Problems solved by technology

In the existing solution, when the distributed cache cluster is upgraded, it is necessary to directly stop the operation of the servers in the distributed cache cluster and restart the new service after cleaning the environment. This solution will stop the service and lose the user's cache data during the upgrade process. It will cause a short-term impact on the user's back-end database

Embodiment Construction

[0065] The present invention will be described in further detail below in conjunction with the accompanying drawings.

[0066] In a typical configuration of the present application, the terminal, the device serving the network and the trusted party all include one or more processors (CPUs), input / output interfaces, network interfaces and memory.

[0067] Memory may include non-permanent storage in computer-readable media, in the form of random access memory (RAM) and / or nonvolatile memory, such as read-only memory (ROM) or flash memory (flashRAM). Memory is an example of computer readable media.

[0068] Computer-readable media, including both permanent and non-permanent, removable and non-removable media, can be implemented by any method or technology for storage of information. Information may be computer readable instructions, data structures, modules of a program, or other data. Examples of computer storage media include, but are not limited to, phase change memory (PRAM...

Abstract

The invention provides a distributed caching cluster upgrading method and equipment. All data on a server with the maximum memory quota in a rank are migrated to other servers of a distributed caching cluster, the server with the maximum memory quota in the rank is taken as an initial current to-be-upgraded server, service programs on the current to-be-upgraded server are upgraded, data on the server ranking just second to the current to-be-upgraded server are migrated to the current to-be-upgraded server, the server ranking just second to the current to-be-upgraded server is taken as a new current to-be-upgraded server, so that stable transitional upgrading can be performed when the servers of the distributed caching cluster are upgraded, and data loss and interruption to external services can be avoided in an upgrading process.

Description

technical field [0001] The present application relates to the computer field, and in particular to a method and device for upgrading a distributed cache cluster. Background technique [0002] In general network systems, the access efficiency of databases or disk files has a crucial impact on the performance of the entire network system. Since the efficiency of the memory cache is much higher than that of the disk, if all data acquisition operations on the database or files can be read from the cache, the reading efficiency will be greatly improved. A single-machine cache system often has limited data storage capacity and external access capabilities, while a distributed cache cluster uses the entire computer cluster to provide external cache services, which solves the problems of insufficient cache capacity and limited access capabilities. In the existing solution, when the distributed cache cluster is upgraded, it is necessary to directly stop the operation of the servers ...
