Concurrent processing request concurrent control method and device, equipment and medium

Abstract

The invention discloses a concurrent processing request concurrency control method, device and equipment and a computer readable storage medium, and the method comprises the steps of respectively setting corresponding identification information for each processing request after each processing request in a concurrent processing request obtains target data needing concurrent processing; determiningtarget identification information from the identification information, and allowing a target processing request corresponding to the target identification information to execute a processing operation on the target data; after the execution of the target processing request is finished, updating the target data of each processing request which is not executed, entering the step of determining thetarget identification information from the identification information, and allowing the target processing request corresponding to the target identification information to execute the processing operation on the target data until each processing request in the concurrent processing requests executes the processing operation. Therefore, the method not only can relatively guarantee the normal execution of each processing request in the concurrent processing request, but also can improve the overall processing efficiency of the concurrent processing request.

Description

technical field [0001] The present invention relates to the field of concurrency control, in particular to a concurrency control method, device, equipment and computer-readable storage medium for concurrently processing requests. Background technique [0002] With the rapid development of information technology, there may be concurrent processing requests when processing target data, so concurrency control methods emerge as the times require. The concurrency control method refers to a control method for each processing request in the concurrent processing requests when the concurrent processing requests perform processing operations on the target data at the same time. The concurrency control methods in the prior art include pessimistic concurrency control and optimistic concurrency control; wherein, pessimistic concurrency control refers to locking the target data when one of the concurrent processing requests executes processing operations on the target data, and other No...

Problems solved by technology

The concurrency control methods in the prior art include pessimistic concurrency control and optimistic concurrency control; wherein, pessimistic concurrency control refers to locking the target data when one of the concurrent processing requests executes processing operations on the target data, and other No processing request can perform processing operations on the target data; therefore, pessimistic concurrency control will affect the normal execution of other processing requests in concurrent processing requests

In optimistic concurrency control, after a processing request performs processing operations on the target data, it is judged whether there are other processing requests to perform operations on the target data again, and if so, an error message is generated after other processing requests perform processing operations, Other processing requests will perform corresponding rollback operations according to the error information. Obviously, this method will seriously affect the processing efficiency of other processing requests in concurrent processing requests, and affect the overall processing efficiency of concurrent processing requests
