Asynchronous Model for Reading Files

An asynchronous model for reading files is still desirable, especially for database people like us. If the requested portion of the file happened to be in the OS cache, the read will be faster. We may spin up a thread to perform the blocking read while keeping the main thread block free. But technically speaking, it is still synchronous and blocking to the OS. It is just the thread that is blocked instead of the main process. So we're just playing games. Part three: DNS or domain name system or server or service resolves domains and host names to network addresses.
