SeaweedFS is a simple and highly scalable distributed file system. There are two objectives: to store billions of relatively small files, and to serve those files fast. Implements an object store with O(1) disk seek and an optional filer with a POSIX interface. Metadata can be stored in one of several RDBMSes. Speaks HTTP(S). Supports multiple access APIs, including S3, HDFS, and WebDAV. Can automatically back itself up offsite. Supports multiple URI formats, with varying degrees of niceness. Large files are chunked transparently to the user.
