Distributed Flow-Based Programming via message queues
Implementation of the Flow-Based Programming using message queues as the communications layer between different processes. Initial message queue transports targeted are AMQP and MQTT.
MsgFlo lets you build robust polyglot FBP systems spanning multiple computers/devices. A node can be implemented in any language, to reuse existing code, libraries and developer know-how.
In FBP each component is a black-box that processes and produces data, without knowledge about where the input data comes from, or where the output data goes. This ensures that a service is easy to change, and facilitates automated testing.
MsgFlo is designed to enable partial and gradual integration into existing systems; by using standard broker/transports, not placing restrictions on message payloads, allowing to use existing queue names, and integrating non-MsgFlo nodes seamlessly.
