- Chunks should not be separated between the main and orphaned folders. The concept of "orphans" or "to be removed" should only be held in-memory. If a chunk server crashes, upon restarting and reconnecting to the master any chunk will be re-marked for removal when speaking to the master. - Implement write on the client - Implement proper operation handles that allow users to wait for specific events - Clean up the read operation for clients - Check that the corner case where read and writes go over the length of the file work correctly - When a client received metadata and starts reading or writing to a chunk server, it should try connecting to all addresses of a chunk servers, not just the first one. - Return the number of bytes read or written in the TinyDFS_Result struct - Make parallel uploads/downloads configurable
