Various systems and methods for maintaining write order fidelity in a distributed environment are disclosed. One method, which can be performed by each node in a cluster, involves associating a current sequence number with each of several write operations included in a set of independent write operations. In response to detecting that one of the write operations in the set is ready to complete, a new sequence number is selected, and that new sequence number is thereafter used as the current sequence number. None of write operations in the set is allowed to return to the application that initiated the write operations until the new sequence number has been advertised to each other node in the cluster. The method also involves receiving a message advertising a first sequence number from another node in the cluster, and subsequently using the first sequence number as the current sequence number.
