Mountpoint for Amazon S3

Judgement

What it is

Developer tool

What it does

A FUSE client from AWS that mounts an S3 bucket as a local filesystem with high read throughput for large sequential workloads.

Adopt it when

Your data-processing or ML jobs read large files from S3 and you want filesystem access without copying the data first.

Watch out

It does not support full POSIX: no renaming, no editing existing files in place, and no directory locking.
