Problems solved by technology

However, this way of using periodic polling to access the master control node requires high polling frequency settings. If the polling frequency is too high, a large number of invalid requests will be generated, which will increase the processing burden of the master control node. If it is low, it will slow down the speed at which the client gets the new service address
It can be seen that the current distributed system still has the problem of not being able to respond in time when the client fails to access the service node

Embodiment Construction

[0031] Exemplary embodiments of the present invention will be described in more detail below with reference to the accompanying drawings. Although exemplary embodiments of the present invention are shown in the drawings, it should be understood that the invention may be embodied in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided for more thorough understanding of the present invention and to fully convey the scope of the present invention to those skilled in the art.

[0032] The present invention is an optimization and improvement made for improving the repairing speed of the failure when the client accesses the service node under the service framework of the existing distributed system. In the embodiment of the present invention, the access failure generally refers to the failure of the client to access the service node. The main reasons for the inability to access are network instability, or the service nod...

Abstract

The embodiment of the invention discloses a distributed system and a management method thereof, and the method comprises the steps: receiving an address updating request sent by a client, with the address updating request being used for obtaining a service node address for providing a service for the client; caching the address updating request; and before the timeout time corresponding to the address updating request arrives, if determining that the service node providing service for the client is migrated from the first service node to the second service node, returning the address of the second service node to the client. When the client fails to request the service, the scheme of the embodiment of the invention can accelerate the fault repair speed and improve the user experience.

Description

technical field [0001] The present invention relates to the field of computer technology, in particular to a distributed system and its management method. Background technique [0002] The service framework of a distributed system usually includes the following components: Client (Client): a client program that provides an interface for users to access services; Service Node (Server): provides users with specific interface logic functions, usually consisting of multiple nodes Composition; master control node (Master): mainly used to manage and schedule service nodes, perform service access authentication for clients, and manage and allocate cluster resources, usually consisting of a single or multiple nodes. A typical distributed system externally provides application programming interface (API) services usually includes the following steps: [0003] 1) The client asks the master control node for the service node address of the required service, and the master control node ...
