Methods, electronic devices, and computer program products for accessing a file

Abstract

Techniques for accessing a file involve determining whether a client requests a permission for a target file, the permission allowing the client to cache data associated with the target file. The techniques further involve in response to determining that the client requests the permission, obtaining pattern information related to an access pattern in which the client accesses the target file. The techniques further involve determining availability of the permission to the client by applying the pattern information to a decision model, the decision model being trained based on training pattern information and training permission information. The techniques further involve providing, to the client, an indication on the availability. Accordingly, access conflicts can be reduced, so that the performance of the client and server can be improved.
