Abstract
In response to a rename request to change a file name at a storage service from a first name to a second name, a workflow comprising at least two atomic operations is initiated. In the first atomic operation, a lock is obtained on a first directory entry for the first name, and an intent record for the rename workflow is stored. In a second atomic operation, a pointer of a second directory entry for the second name is modified, and an indication of the pointer modification is stored. In a third set of operations, the intent record is deleted, the lock is released, and the first directory entry is deleted.
