The present disclosure discloses a method, a system and a server of removing a distributed caching object. In one embodiment, the method receives a removal request, where the removal request includes an identifier of an object. The method may further apply consistent Hashing to the identifier of the object to obtain a Hash result value of the identifier, locates a corresponding cache server based on the Hash result value and renders the corresponding cache server to be a present cache server. In some embodiments, the method determines whether the present cache server is in an active status and has an active period greater than an expiration period associated with the object. Additionally, in response to determining that the present cache server is in an active status and has an active period greater than the expiration period associated with the object, the method removes the object from the present cache server. By comparing an active period of a located cache server with an expiration period associated with an object, the exemplary embodiments precisely locate a cache server that includes the object to be removed and perform a removal operation, thus saving the other cache servers from wasting resources to perform removal operations and hence improving the overall performance of the distributed cache system. |
