[aerogear-dev] [Unified Push Server] Improving the message delivery to GCM

Tue Dec 2 11:41:40 EST 2014

Hello!

right now, we use HTTP (via Google's Sender), and they only allow 1000
tokens, per request to GCM, that means, we have a lot of (blocking)
requests (see below trace).
We loop over the our 'processGCM', which internally invokes the HTTP sender
from google:
https://github.com/aerogear/aerogear-unifiedpush-server/blob/master/push/sender/src/main/java/org/jboss/aerogear/unifiedpush/message/sender/GCMPushNotificationSender.java#L118-L129
(they use HttpUrlConnection inside of that 'sender')

I see some improvements here:
* make the requests to google concurrent
* use persistent XMPP connection (https://issues.jboss.org/browse/AGPUSH-36)

Regarding AGPUSH-36 we could extract that into a tiny libray, to be used by
UPS (like we did with others).

Greetings,
Matthias
