Abstract
Cancelling file system operations at a file system client of a distributed file system is disclosed. In various embodiments, an indication is received to send locally-stored file system operations to a remote file system metadata server. A dependency graph or other data structure reflecting dependencies between the locally-stored file system operations is used to identify a set of locally-stored file system operations the members of which are fully dominated by a create-delete pair of operations comprising the set. The locally-stored file system operations comprising the set are cancelled, without being sent to the remote file system metadata server.
