An in-memory queue triggerer executes an orchestration at-least-once, possibly at-most-once (presuming that the orchestration in question has some rollback behaviour) when the given in-memory queue contains at least one message.
It is a transport asynchronous queue, which is not persistent, so all messages in the queues will disappear on server shutdown. The data from the queue message itself is provided to the stream.
