Best Way to Send Data from C++ program to Rails Server

I have a C++ program that is constantly generating a large amount of data that need开发者_StackOverflow社区s to be sent to a Rails server. Both the program and the server are on the same machine running Suse Linux.

What is the most efficient and simple solution for this?

Sockets are the way to go. If you want some good asynchronous and cross-platform sockets in C++ your best bet, probably, will be boost::asio.

You could store the data the way you want (file or database).

The only tough point is to make your Rails app aware the C++ program is completed.
I'd strongly advise you to store this information in cache so that it won't cost much to check this every period you need.

You could use sockets since both your programs are residing on the same local machine, and in general it should be pretty straight-forward to send the serialized data over a local socket. Since the socket is using an internal buffer, the transfer time should be very fast. Your C++ program can either push data to the Rails server, or you can have the Rails server poll the C++ program providing you're setting up a cache in your C++ program to store the data in between polling calls. The push method would probably work best though.
