Thanks for educational comments! I need to update those old statements. It was started originally as an object store only. The blobs are read-modify-write, but a file can have many blobs. So the whole file does not need to be read-modify-write, unless it is a small file. The redundancy is managed via scriptable admin commands.

Great to see you here! I understand your unit of smallest write is a blob. How large are blobs? How does their identifier look like?

  There are actually no limit for blob size. The clients decide the blob size. It is limited by available memory and concurrency. By default, the filer client uses 8MB. Each identifier is as <volume_id, file_key, cookie>. With volume_id, you can locate the volume server. So the volumes are portable and can be moved around.
