FastDFS Overview: Principles, Architecture, Upload/Download Process, Synchronization, and Storage Management

FastDFS is a lightweight, open‑source distributed file system written in C that uses a three‑component architecture—client, tracker server for load‑balancing and discovery, and storage servers with push‑based binlog replication—to handle high‑concurrency upload/download of small to medium files, support group‑wide synchronization, optional trunk storage, Nginx anti‑leech integration, and extensible deduplication via FastDHT.
