The main driving force behind the development of the Smarkets streaming API is efficiency. Many other applications in our industry rely on “polling” a service in order to provide a real-time view of changing data. While the streaming API can be used in a “synchronous” manner by making a request and waiting for a response, it is often far more efficient to design an application asynchronously. Asynchronous messaging allows for more flexible patterns and techniques like pipelining.
The streaming API also uses framed protocol buffers to define the wire format, so parsing messages is relatively fast and simple. We will endeavour to maintain backwards compatibility as we release newer revisions of the API. Protocol buffers definitions provide a decent facility for doing so.
In selecting a software license, we aimed to choose one which allows third-party application developers flexibility in using the code we provide.
