Problems solved by technology

[0002] With the development of Internet technology, the centralized system cannot meet the business scenarios of complex business and high concurrency, and then evolves to the distributed system to solve the system scalability, maintainability and performance bottleneck problems of the centralized system
However, distributed systems also bring a certain degree of complexity.
In a distributed system, due to the fact that an application is published by multiple nodes, when multiple requests perform concurrent operations on stateful data, that is, critical resources, there may be errors in which the operation results do not follow the expected results, that is, there are dirty data

Abstract

The embodiment of the invention discloses a resource acquisition method which is applied to a distributed system. The method comprises the following of generating a resource application according to aservice to be executed, and sending the resource application to a distributed lock; judging whether a distributed lock is acquired or not, and if the distributed lock is not acquired, monitoring thedistributed lock; and when monitoring that the distributed lock is released by the application node of the acquired distributed lock, sending the resource application to the distributed lock again. The invention further provides a resource allocation method, a resource acquisition and allocation device and a computer readable storage medium. According to the invention, orderly access to critical resources can be realized, and the consequence of dirty data is prevented.

Description

technical field [0001] The present invention relates to the technical field of distributed systems, in particular to a resource acquisition and allocation method, device and computer-readable storage medium. Background technique [0002] With the development of Internet technology, the centralized system cannot meet the business scenarios of complex business and high concurrency, and then evolves to the distributed system to solve the system scalability, maintainability and performance bottleneck problems of the centralized system. However, distributed systems also bring a certain degree of complexity. In a distributed system, due to the fact that an application is published by multiple nodes, when multiple requests perform concurrent operations on stateful data, that is, critical resources, there may be errors in which the operation results do not follow the expected results, that is, there are dirty data. Contents of the invention [0003] Based on this, it is necessary...
