Problems solved by technology
In a distributed environment, the processes may not even be on the same physical machine, so it is necessary to store the mark in a place that all processes can see. After one thread, the lock cannot expire, or the lock cannot be actively released, or the lock is lost

The invention discloses a distributed lock implementation method and device, electronic equipment and a storage medium. The method comprises the steps that a configured distributed data storage cluster and a connection address and a connection pool of a cluster management mechanism are acquired, keywords of threads needing to be locked are created, and lock calling information is acquired; acquiring an asynchronous monitoring task released by the lock according to the lock calling information; according to the asynchronous monitoring task of the lock release, obtaining information that the service logic execution of the locking thread is completed and the lock release is performed; and deleting the asynchronous monitoring task released by the lock, and obtaining other threads waiting for obtaining the lock to obtain the lock. According to the method and the device, the lock can be automatically continued before the service logic execution of the locking thread is not finished, so that the lock cannot be released in advance, and after the execution of the locking thread is finished, other threads waiting for obtaining the lock timely obtain the message, so that the thread waiting for obtaining the lock is prevented from circularly waiting for requesting for locking all the time, and the consumption of a processor is reduced.
Description
technical field [0001] The invention relates to the technical field of software testing, in particular to an implementation method, device, electronic equipment and storage medium of a distributed lock. Background technique [0002] A distributed lock is an implementation of a lock that controls access to shared resources between distributed systems, and its main problem is to ensure data consistency. In a single-process system, when there are multiple threads that can change a variable at the same time, it is necessary to synchronize the variable or code block so that it can linearly execute and eliminate concurrent modification of the variable when modifying this variable. In order to realize that multiple threads can only have one thread executable in the same code block at a time, a mark needs to be marked somewhere. This mark must be visible to every thread. When the mark does not exist, the mark can be set , the remaining subsequent threads find that there is already ...
