Scaling Financial Transaction using 0MQ and JSON

Sign up or log in to save this to your schedule and see who's attending!

Rebuilding legacy apps with open source libraries and tools is the most fun I have had yet. For over a year, I have been updating legacy 4GL/Windows applications to Linux and C++. A primary hang-up of the old system is its lack of scalability. In order to design the replacements with more breadth we implemented 0MQ (zeromq.org) for our communications protocol. When the messages you send are in XML you can easily save another 30% in message size just by switching to JSON (nlohmann/json). The JSON works well with 0MQ as its primary message input is char*. Here using scaled down version of our production code, we will demonstrate how we use it and what we learned so far.
