Message Broker System and Method

A message broker system can include a message broker. The message broker can be configured to receive the message instances output as input message instances, store the input message instances in a message store, alter the structure or content of the input message instances according to a message brokering model to generate output message instances and provide output message instances to one or more downstream processors. According to one embodiment, input message stream processing can be decoupled from output message stream processing by the message broker.
