Resource isolation method and device for distributed database system, and server

Abstract

Embodiments of the invention provide a resource isolation method and device for a distributed database system, and a server. The distributed database system comprises a plurality of servers; a plurality of containers are arranged on each server; each container occupies a pre-allocated resource in the server which the container belongs to; and each container corresponds to a database instance. Themethod comprises the following steps of receiving a service outside the distributed database system or a to-be-processed request of a tenant; sending the to-be-processed request to the database instance allocated to the service or the tenant; and processing the to-be-processed request through each container corresponding to each database instance allocated to the service or the tenant. According to the resource isolation method and device, the service or the request of the tenant can be processed through the container corresponding to each database instance allocated to the service or the tenant, and the request can be processed in a server resource which is allowed to be used by the corresponding container according to the service or the tenant, so that different service or tenant resources are isolated.

Description

Technical field [0001] The present invention relates to the field of database technology, in particular to a resource isolation method, device and server of a distributed database system. Background technique [0002] With the rapid development of Internet business and big data technology, the amount of data that is required to be processed concurrently by the database system is increasing, and the stock of data is also continuously growing. Various manufacturers and enterprises design and implement their own distributed database systems. In order to solve the resource competition problem caused by the use of the same database system for multiple businesses, the current common method is to deploy a separate cluster for each business (or tenant), and physically isolate the hardware between different businesses through the cluster. Resource competition, to solve the problem of resource allocation and competition between businesses (or tenants). [0003] However, if the number of se...

AI Technical Summary

Problems solved by technology

[0003] However, if the number of services and clusters is close to 1:1, the operation and maintenance management costs are high

Especially in scenarios with many business types, it is difficult to manage a large number of small clusters

Moreover, since physical machines need to be allocated separately for each cluster, resource waste is serious for small-scale businesses

For example, this problem will become more prominent after deployment on the cloud, which will intensify the hardware investment of the cloud service provider.

In addition, the clusters are completely isolated and cannot access each other

[0004] Therefore, physically isolating the competition for hardware resources between different businesses will easily lead to increased management and operation costs and inefficient utilization of machine resources.
