A '''log-structured filesystem''' is a [[file system]] design first proposed in 1988 by [[John K. Ousterhout]] and [[Fred Douglis]]. Designed for high write throughput, all updates to data and metadata are written sequentially to a continuous stream, called a log. The design was first implemented by Ousterhout and [[Mendel Rosenblum]].
