"symbol('x-opt-delivery-time')" would be what you need.On Thu, 9 May 2019 at 16:34, Neil Dunbar <[email protected]> wrote: > > Hi all, > > I’m having a bit of trouble using the scheduled delivery function in Artemis > (2.6.4) in an AMQP protocol, via the Qpid-Proton Python library. > > From what I can tell, this should work (from the simple sender example in the > Proton repo) > > from datetime import datetime as dt, timezone as tc > > deltime = int(dt.utcnow().replace(tzinfo=tz.utc).timestamp() * > 1000.0) + 120000 > anns = {'x-opt-delivery-time' : deltime} > while event.sender.credit and self.sent < self.total: > msg = Message(id=(self.ts * 1000000 + self.sent+1), > body={'sequence':(self.sent+1)}, annotations=anns) > > event.sender.send(msg) > self.sent += 1 > > The messages are properly queued, but delivered instantly. > > I’m guessing that there’s some property which needs to be set at the broker > level, but not quite sure what. > > No doubt there’s some obvious setting that I’m missing, so would appreciate > the help. > > Cheers, > > Neil
