Method, device and system for realizing distributed automatically-increasing counting

Abstract

The invention discloses a method, a device and a system for realizing distributed automatically-increasing counting, which relates to the field of cloud computing and is used for improving execution efficiency of distributed automatically-increasing counting and accuracy of counting results. The method provided by the invention comprises the following steps: preserving copies of counting results of an automatically-increasing counter on a plurality of servers in a distributed buffer system in the filed of cloud computing; selecting a latest counting result in the counting results of a same automatically-increasing counter on each server for performing automatically-increasing counting operation when performing each automatically-increasing counting operation, thus effectively ensuring the accuracy of the counting results. According to the method, present automatically-increasing counting operation can be determined to be successful only by confirming the number of the server copying the counting results successfully to reach set threshold, so that the execution efficiency of the automatically-increasing counting operation is improved to some extent.

Problems solved by technology

[0005] At present, the accuracy, concurrency, availability and efficiency of distributed self-increment counters are key issues that are difficult to balance

Under the existing technology, systems that usually guarantee concurrency and accuracy cannot achieve high availability. For example, when any node fails, the overall service will be interrupted. After all the tasks of the failed node are transferred to other nodes for execution, It takes a long time to restore the overall service, which reduces the service efficiency of the distributed self-incrementing counter to a certain extent; further, under the existing technology, the system that ensures the accuracy and availability cannot realize multiple counters. Request concurrency, for example, when multiple self-increment counts of the same value are sent to the server at the same time, only one request can be allowed to succeed, and other requests will return failure, and the service terminal that fails the request must retry, which also reduces to a certain extent The service efficiency of the distributed self-increment counter is improved; further, the system that guarantees concurrency and availability cannot guarantee the accuracy. For example, when multiple self-increment count requests are executed at the same time, the counting results between the servers are not coordinated , resulting in inconsistent counting results and affecting the counting accuracy
