Described are embodiments for allowing clients that access a distributed file system to locally cache directory metadata. The client may request a read lease which allows the client to cache the directory metadata locally and service requests received from the same application which originally requested the directory metadata using the cache. In addition, the client may also request a handle lease which allows a client to delay the closing of a directory handle and allow the handle to be reused to service subsequent directory metadata requests from the same or a different application. A client may also request a write lease which allows an application on the client to modify the directory metadata, such as by creating or deleting new files in the directory, or changing their attributes, and cache those changes.
