&quot;Log-structured file system&quot; or &quot;journaling file system&quot; is often how such things are described. The notion being that the primary operation of interest is appending new data records, rather than modifying existing data.<p><a href="https:&#x2F;&#x2F;en.wikipedia.org&#x2F;wiki&#x2F;Log-structured_file_system" rel="nofollow">https:&#x2F;&#x2F;en.wikipedia.org&#x2F;wiki&#x2F;Log-structured_file_system</a><p>The use of the term &quot;log&quot; in some contexts implies concepts like lossy, unimportant, non-durable, etc. However, in the context of log-structured file systems or journaling file systems, the sense that&#x27;s intended is append-only as a primitive, atomic, consistent, durable (replicated) operation.
