AIR is AMQP Interoperable RPC ============================= When using AMQP to handle the majority of inter-system comms it is sometimes useful to allow point-2-point RPC-like calls. AIR provides a simple framework that allows request/response messages to be sent via AMQP. At the AMQP level services are addressed using a pre-shared routing key (which may be shared) and replies are sent to an ad-hoc UUID using the standard AMQP reply-to header. AIR uses json to encode args in the RPC call/response. The AIR calling wrapper contains a message ID, parameters and a deadline. The AIR response wrapper contains a message ID and the response.
