What does 'duration' mean?

Hi @jeffrichiefs duration is the time needed for the complete request / reply process.

Client (Send) -> NATS -> Server (Reply) -> NATS -> Client (Received)

Thanks @StarpTech - how often does Hemera poll the queue? That would be the arrows between the calls.

Answer 3 · 2018-04-10T20:51:55.000Z

@jeffrichiefs which queue? The messages are routed directly through NATS. NATS act as a router.

By queue I meant NATS - Hemera looks for new messages every so often or am I thinking about this wrong?

Answer 5 · 2018-04-10T21:22:06.000Z

Yes, there is no pull mechanism. NATS notify hemera about updates.
