Resource allocation method and device

Abstract

The embodiment of the invention discloses a resource allocation method and device. The resource allocation method comprises the following steps: receiving a resource request sent by a client; taking out target resource data from a preset cache, wherein the operation of the preset cache has the atomicity, and the preset cache stores resource data read in advance from a database; and returning the target resource data to the client. Through the resource allocation method and device, the query pressure of the database can be reduced, and the concurrency performance of the system can be improved.

Description

technical field [0001] The present invention relates to the field of network technology, in particular to a resource allocation method and device. Background technique [0002] Many application systems, especially resource management systems, will initialize some public relations resources for allocation to each user. For example, the public cloud platform provides functions and services for purchasing elastic public IP (Internet Protocol, Internet Protocol) addresses. Among them, a An IP address can only be allocated to one user. When multiple users request to purchase an elastic public network IP address at the same time, it is very easy to have duplicate IP address allocation, that is, the problem of repeated allocation of resources under high concurrency. [0003] At present, optimistic locking is mainly used, based on the data version (Version) recording mechanism, to prevent repeated allocation of resources under high concurrency. Specifically, in the solution based o...

Problems solved by technology

[0004] Through the above method, the use of optimistic locking can improve the situation of repeated allocation of resources, but for each request, the data needs to be fetched from the database again, which increases the query pressure of the database and leads to low concurrency performance of the system
