Coarse Grained + less interactions between client/server + less network overhead & possibility of re-using the same network connection to send messages to the Push Networks (at least for APN) + simple client side - much data exchanged in each interaction between client/server - complex server side _______________________________________________ aerogear-dev mailing list aerogear-dev(a)lists.jboss.org https://lists.jboss.org/mailman/listinfo/aerogear-dev _______________________________________________ aerogear-dev mailing list aerogear-dev(a)lists.jboss.org https://lists.jboss.org/mailman/listinfo/aerogear-dev

It's easier for SimplePush because we control the push network so we can add that type of functionality. For the other networks though, if they can't accept multiple push messages in a single batch, you're still going to have to loop over them all and do those sends. With that in mind, IMO this should only be added if the push networks can handle it. Otherwise, this idea seems like it is going to muddy the waters in terms of mixing business logic into the UP server which we definitely don't want to do. +1, no mixing Again, IMO, if you are sending out several hundred thousand personalized messages via push, you're probably doing it wrong and need to reconsider the way your app is structured. Push messaging is not a mass e-mail system. exactly On Sep 27, 2013, at 2:12 AM, Apostolos Emmanouilidis <aemmanou(a)redhat.com&gt; wrote: I received some feedback for the aerogear-unifiedpush-server.
