## What it is
Cloud Storage FUSE (gcsfuse) is a user-space FUSE file system that mounts Google Cloud Storage buckets as local directories with standard file system semantics. It is an open-source, Google-supported CLI tool optimized for AI/ML workloads with features like file caching, parallel downloads, and streaming writes.

## Use cases
- mount a gcs bucket as a local folder on linux
- read training data from cloud storage as a file system
- speed up model checkpoint writes to gcs
- serve large model files with cached parallel downloads
- use gcs buckets as kubernetes pod volumes via csi driver
- access cloud storage objects with standard file tools

## When to choose
- applications expect POSIX-like file access to object storage
- AI/ML training or serving pipelines reading data from GCS
- you want to avoid rewriting code that uses local file APIs

## When to avoid
- you need full POSIX semantics like locking or strong consistency everywhere
- simple object uploads/downloads where the GCS API or SDK is more efficient
- non-Google cloud object storage
