Re: [google-appengine] Re: is it possible listen to a pub/sub topic without a subscription?

[Nick Pomfret]

I'm not sure I understand your answer.

Maybe my question was unclear...  I am publishing messages onto  a topic.
If my app isn't running I'm happy for those messages to disappear. AND I
don't want a backlog of messages when I switch my app on.  I want topic
behaviour, not queue behaviour (which is what I'm getting when I create a
subscriber).

[google-appengine] is it possible listen to a pub/sub topic without a subscription?

[Nick Pomfret]

I'm wondering if it's possible to broadcast messages on a topic and have a 
process listen to them but without a subscription?

The reason is that I don't care about losing messages if say my application 
was switched off.  And when it's switched back on I only want to receive 
message published since the moment it was switched on.
