# The Google File System

GFS is a useful first distributed storage paper because the assumptions are explicit: large files, append-heavy workloads, commodity failures, and a master that keeps metadata tractable.

## Paper details

- Authors: Ghemawat et al.

- Venue: SOSP 2003

- Track: Systems

- Difficulty: Easy

- Reading time: 40 min

- Original paper: https://research.google/pubs/the-google-file-system/

## What you will learn

- How chunks, chunkservers, and a master split data from metadata.

- Why workload assumptions can simplify a distributed file system.

- How leases, replication, and recovery handle common machine failures.
