Log-structured filesystem

A Log-structured File System (LFS) is a method of organizing data on storage devices by writing all updates sequentially to a continuous log. Instead of overwriting existing data, it appends new data to the end of the log, making write operations faster and more efficient. Over time, the system consolidates and cleans the log to remove outdated information. This approach is especially beneficial for applications with many small, frequent writes, such as databases or SSDs, because it reduces seek time and improves overall performance while maintaining data integrity.
