Mountpoint for Amazon S3 is a high-throughput FUSE file client that mounts an Amazon S3 bucket as a local file system. It translates file operations like open and read into S3 object API calls, optimized for reading large objects concurrently and writing new objects sequentially.

Use cases

• mount an s3 bucket as a local filesystem
• read large files from s3 without downloading them first
• access a subset of s3 objects from a large dataset
• upload files directly to s3 with cp
• run data processing workloads that read from s3 across many instances

When to choose

• your application needs high read throughput to large S3 objects from many clients
• you want file-based access to S3 without managing local copies
• you write new objects sequentially from a single client

When to avoid

• your workload requires full POSIX semantics like directory renames or symlinks
• you frequently edit existing files in place
• you need random writes to existing objects
