Shared resource access processing method and device, electronic equipment and storage medium

Abstract

The invention relates to the field of Internet, and provides a shared resource access processing method and device, electronic equipment and a storage medium. The method comprises the steps that it is determined that a target thread obtains a distributed lock accessing shared resources, an asynchronous compensation thread is created for the target thread, and the asynchronous compensation thread is used for compensating for the time when the target thread occupies the distributed lock; and when determining that the time of occupying the distributed lock by the target thread is greater than a preset time period, the distributed lock is released. The asynchronous compensation thread is created for the target thread, so that midway release of the distributed lock caused by too long execution time of the target thread is avoided; meanwhile, by setting a preset time period, it is avoided that after the target thread is abnormal, the time for occupying the distributed lock is too long, and access of other threads to the shared resources is affected; and the distributed lock is released immediately when the thread occupies too long time or is terminated, so that the safety access efficiency of shared resources with large instantaneous concurrency in a distributed environment is improved.

Description

Technical field [0001] The present invention relates to the field of Internet technologies, in particular to access processing methods, devices, electronic devices, and storage media that share resources. Background technique [0002] With the development of the Internet, there is more and more access to shared resources, so you need to achieve access control of shared resources by locking. The lock can be seen as a thread synchronization mechanism for accessing the shared resource in the case, and all threads are provided in the same JVM (Java Virtual Machine, Java Virtual Machine). The lock mechanism can synchronize the shared resource; in the distributed environment, multiple different threads need to be synchronized with Java, which cannot be implemented with Java when the shared resource is synchronously. [0003] The prior art is mainly accessed by the shared resource by using the optimistic lock of the database, but for the instantaneous and launched scenarios, such as Int...

AI Technical Summary

Problems solved by technology

Locks can be regarded as a thread synchronization mechanism for accessing shared resources under multi-threaded conditions. For single-process applications, all threads are in the same JVM (Java Virtual Machine, Java Virtual Machine) process, using the Java language provided The lock mechanism can control the shared resources synchronously; in a distributed environment, when multiple different threads need to access the shared resources synchronously, it cannot be achieved with the Java lock mechanism.

[0003] The existing technology mainly uses the optimistic lock of the database to realize the access control of shared resources. However, for scenarios with a large amount of instantaneous concurrency in a distributed environment, such as the access to shared resources in the Internet of Things, if only optimistic locks are used, it is often unable to satisfy users.
