Manta was one of the most exciting technologies I touched five years ago. Color me impressed when I inline `sed` replaced 3TB of logs (2.5 years worth) in 30 seconds on our manta storage.
Used it for the backing store for the npm's registry when tarballs were moved out of CouchDB. Managed to cope with us flushing the CDN cache (Fastly) and not fall over with users downloading packages.
