ACCESS CONTROL METHOD AND APPARATUS

Embodiments of the present application relate to an access control method and apparatus, relating to the technical field of computers. The method is applied to a first node comprising a first storage space, the first storage space comprising multiple sub-storage spaces. The method comprises: the first node receiving an access request from a second node, the access request being used to access a first sub-storage space in the first storage space, and the first sub-storage space being one of the multiple sub-storage spaces; the access request comprises space access information and a first access type, the space access information being used to indicate the first storage space and the first sub-storage space. The first node controls access of the second node to the first sub-storage space according to the space access information and the first access type. Since granularity of the first sub-storage space is smaller than that of the first storage space, the present method can control the second node to access a s
