## What it is
GeeseFS is a high-performance FUSE file system written in Go that mounts S3-compatible buckets (Yandex Object Storage, Amazon S3) as local file systems. It improves on prior S3 FUSE implementations with aggressive parallelism and asynchrony for better small-file and metadata performance.

## Use cases
- mount an s3 bucket as a local filesystem
- access object storage files with posix-like semantics
- use s3 as backend storage for kubernetes via csi
- run applications that need file access to cloud storage
- improve small-file performance over s3fs or goofys

## When to choose
- you need to mount S3 or Yandex Object Storage buckets locally with better performance than s3fs/goofys
- you need POSIX-ish features like symlinks, truncate, fsync, or chmod on object storage
- you want a Go-based, actively maintained S3 FUSE driver

## When to avoid
- you need full POSIX compliance such as hard links or file locking
- you require correct file permissions and metadata on non-Yandex S3 providers
- you only need simple object upload/download rather than a mounted filesystem
