But this way always results in part of the service being unavailable
[0005] Another way in the prior art to deal with the burst traffic exceeding the service capacity is to add servers in the cluster. However, the disadvantage of this method is that the response is slow, especially because the burst traffic exceeding the service capacity is generally abnormal. Growth. When adding a machine, it takes time to prepare the machine and synchronize the data. During this period, the search server cluster may enter a state where some services are unavailable. In addition, manual intervention is required during the machine addition process, which is not intelligent enough , the response is lagging, and it cannot quickly respond to sudden traffic spikes

Embodiment Construction

[0051] In order to make the above objects, features and advantages of the present application more obvious and comprehensible, the present application will be further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0052] Currently, search engines support fast text query by building an inverted index (inverted index) for the text to be queried. The inverted index comes from the need to find records based on the value of the attribute in practical applications. Each entry in such an index table includes an attribute value and the addresses of records having the attribute value. Since the attribute value is not determined by the record, but the position of the record is determined by the attribute value, it is called an inverted index.

[0053] Taking the product search on a large e-commerce website as an example, by establishing an inverted index for the title of the product, the query process of the product is as ...

Abstract

The invention provides a service capability control method of a server cluster. The service capability control method comprises the steps of monitoring service state information of servers in a cluster, and judging whether the service state information exceeds a preset threshold or not, if so, determining the quantity of the servers issued by subsequent service requests according to the service state information, wherein the quantity of the servers issued by the subsequent service requests is smaller than that of the servers issued by the service requests when the service state information does not exceed the preset threshold; and determining corresponding quantity of target servers in the cluster according to the preset rule and according to the quantity of the servers issued by the subsequent service requests, and issuing the received service requests to the target servers. The burst traffic exceeding the service capability can be quickly coped with by the method provided by the invention, and service without interruption is also ensured.

Description

technical field [0001] The present application relates to the technical field of server clusters, in particular to a server cluster service capability control method and system. Background technique [0002] At present, all kinds of large enterprises and large websites use server clusters for resource management. The so-called server cluster refers to the concentration of multiple servers for the same service, which appears to the client as if there is only one server. The cluster can use multiple computers for parallel computing to obtain high computing speed, and can also use multiple computers for backup. Even if one of the machines fails, the entire search server cluster can still operate normally. [0003] Each server cluster has its own service limit. When faced with traffic exceeding its own service capacity, it will cause the search server cluster to enter a partially unserviceable state, or even completely unserviceable state. For example, if the resources of the ...
