Method and device for physical isolation of distributed cluster based on lucene

Abstract

The invention discloses a method and a device for physical isolation of a distributed cluster based on lucene. The method comprises an index creation process, and the index creation process comprisesthe steps of querying a current cluster resource list and a current index relationship list stored in a distributed memory according to an index creation request of a service, and obtaining a use range of a server to which the service is pre-allocated in a cluster; obtaining a server list which can be used by the service according to the inquired use range of the server; and according to the current running state of each server in the server list, allocating the fragments of the index to be created to each server, the fragments including a main fragment and / or an auxiliary fragment. Accordingto the invention, by pre-allocating the server range in the cluster to the service (i.e., dividing cluster resources for the service), physical isolation of different services in the cluster is realized, and the response rates of all services (the response rate of the cluster is at a second level) are significantly improved.

Description

technical field [0001] The invention relates to the technical field of cluster management, in particular to a method and device for physical isolation of a Lucene-based distributed cluster. Background technique [0002] At present, there are usually two ways for multiple businesses to use Lucene-based distributed clusters (such as Elasticsearch clusters). One way is to index different businesses directly on the same Lucene-based distributed cluster, in this way to make full use of cluster resources. Another way is to establish multiple clusters, so that each service corresponds to an independent cluster, and in this way, interference caused by different services can be avoided. [0003] Although the first method can make full use of cluster resources, the business is in a tightly coupled state, which will cause interference between different businesses, resulting in some significant performance problems. For example, one business A has a relatively large amount of data, an...

Problems solved by technology

[0005] In order to solve the problems of the prior art, the embodiment of the present invention provides a method and device for physically isolating a lucene-based distributed cluster, so as to overcome the problems existing in the prior art when multiple services share a distributed cluster, the business The problem of mutual interference caused by tight coupling, and when each business establishes an independent distributed cluster, the cluster will become more and more, which increases the complexity of cluster operation and maintenance, etc.
