A miniature S3-to-S3 proxy that accepts incoming requests, hashes the uploaded file, stores their desired path in a MariaDB database, along with the hash, and then uploads the original file to a backing S3 server named after the hash to offer file-level deduplication. Also implements an acceleration server called Rivet that allows users to request media be added to the pool by URL without a potentially wasteful download/upload. Learn more.
