And if you want to improve latency you can use fifo's on Unix or anonymous pipes on Windows and run a thread to send your data while it's writing since those methods are synchronous. man popen (you open write in one thread and open a read in another) http://msdn.microsoft.com/en-us/library/windows/desktop/aa365141%28v=vs.85%29.aspx On Windows you get 2 handles that you pass the read handle to your other thread.
Remember to send a 2nd item (last packet) with how many bytes you sent so the client knows it got what it was supposed to. Otherwise you're sure to get a truncated db some time and die on the client.

I'm sure there may be other more direct-to-memory approaches, perhaps using a custom VFS. However, this approach should be simple and easy, and would not require any special serialization library-- just standard file I/O.
