A Log-Structured File System (LFS) is a type of file system designed to optimize write operations by organizing data in a sequential log format. Instead of updating files in place, LFS appends new data to the end of a log, which improves performance, especially for write-heavy workloads. This approach minimizes disk seeks and enhances the efficiency of storage devices. To maintain data integrity and manage space, LFS periodically performs a process called garbage collection. This process reclaims space by consolidating fragmented data and removing obsolete entries from the log. Overall, LFS is particularly beneficial for systems that require high write throughput and efficient data management.
