Distributed system, distributed service processing method and correlated device

Abstract

The invention discloses a distributed service processing method. The method comprises that: a main server acquires query keywords carried in a distributed service processing request; the main server makes a hashing to the query keywords to obtain a hash value of the query keywords; if the request is a logic service processing request, the main server finds the address of a logic server corresponding to the hash value in a mapping table of the logic server, and sends the request to the corresponding logic server for processing; if the request is a data service processing request, the main server finds the address of a data server corresponding to the hash value in a mapping table of the data server, and sends the request to the corresponding data server for processing. The invention also correspondingly discloses a distributed service processing system and related devices. The method provided by the invention embodiment realizes that the logic service processing request is sent to different logic servers, and also realizes that the data operation service processing request is sent to different data servers.

Description

technical field [0001] The present invention relates to the technical field of the Internet, in particular to a distributed system, a distributed service processing method and related devices. Background technique [0002] With the increase of Internet business and the expansion of Internet users, a single server is far from meeting the needs of Internet business processing. Therefore, the background of the Internet has begun to develop towards a distributed system. [0003] A distributed system is a system that performs business processing on a multi-processor architecture interconnected by a communication network. To coordinate a distributed system composed of a large number of servers into an organic whole, an effective distributed business processing solution is required, including: sending the user's logical business processing requests to different logical servers for processing, and data operation business Processing requests are sent to different data servers. At t...

Problems solved by technology

[0006]After studying the existing technology, it can be seen that the DNS server method can only realize the logic business processing request initiated by the client to be sent to different logic servers for processing. It is not possible to send data operation business processing requests to different data servers

[0007]Furthermore, although the logical server in the distributed system can be conveniently increased or decreased by using the DNS server, since the client will cache the logical server returned by the DNS server address, when the client accesses the domain name again, the client will no longer ask the DNS server for the address of the logical server corresponding to the domain name, but directly access the logical server corresponding to the cached address, which prevents the newly added logical server from being accessed as soon as possible. The client is aware of this, resulting in uneven distribution of traffic carried by the logical server in the distributed system, and if the server corresponding to the cached address no longer exists, it will cause the client to be unable to access
