NMR Flow types

The flow type determines the mechanism by which the Normalized Message Router (NMR) Broker sends messages from one BC/SE to another.

...

• The flow implementation of abstract doSend Method determines how the message sending mechanism works

STFlow

STFlow = "Straight Through" Flow. This is the simplest mechanism. There is no staging or buffering.

SedaFlow

SEDA = "Staged Event Driven Architecture" Flow. SEDA decomposes a complex, event-driven application into a set of stages connected by queues.

...

• When the SedaQueue Worker (run Method) finds (dequeues) an ME, it processes it in another JCA Worker thread created solely for that purpose

JMSFlow
