Abstract
This document relates to data storage techniques. One example can buffer write commands and cause the write commands to be committed to storage in flush epoch order. Another example can maintain a persistent log of write commands that are arranged in the persistent log in flush epoch order. Both examples may provide a prefix consistent state in the event of a crash.
