Abstract

The invention provides a method and a device for implementing a distributed lock based on a network, and a medium. The method comprises the following steps: firstly, receiving a locking operation request of a distributed lock sent by at least one client, adding at least one client into a client queue for sequencing, sequencing on the basis of time or priority, then obtaining a current client whichfirstly performs a locking operation request, and judging whether the locking request of the current client is a synchronous locking request or an asynchronous locking request; different locking strategies are used according to different locking requests, so that the locking request corresponding to the current client side meeting the conditions obtains the distributed lock and accesses the resource information, and if the conditions are not met, locking failure information is returned. According to the content of the invention, effective access of shared resources is realized, and the problem of reentrancy of the distributed lock, the problem of single-point failure of the distributed lock service and dependence of the distributed lock service on third-party software are solved.

Description

technical field [0001] The present application relates to the field of computer technology, specifically to the field of Internet technology, and in particular to a method, device and medium for implementing a network-based distributed lock. Background technique [0002] At present, almost all large-scale websites and application deployments are distributed. Data consistency in distributed scenarios is an important topic. The distributed CAP theory tells us that "any distributed system cannot satisfy Consistency, Availability, and Partition Tolerance at the same time, and can only satisfy two at the same time.". Therefore, at the beginning of many system designs, trade-offs have been made for these three items. In most Internet systems, it is necessary to sacrifice strong consistency in exchange for high availability of the zone, and the system often only needs to ensure final consistency. [0003] The prior art solutions include three implementations of distributed locks...
