A '''log-structured filesystem''' is a [[file system]] in which data and metadata are written sequentially to a [[circular buffer]], called a [[log file|log]]. The design was first proposed in 1988 by [[John K. Ousterhout]] and Fred Douglis and first implemented in 1992 by Ousterhout and [[Mendel Rosenblum]] for the Unix-like [[Sprite (operating system)|Sprite]] distributed operating system.<ref name="rblub">{{citation|title=The Design and Implementation of a Log-Structured File System|url=https://people.eecs.berkeley.edu/~brewer/cs262/LFS.pdf|publisher=University of California, Berkeley|year = 1991|first1 = Mendel Rosenblum.|last1 =John K.
