I am reading Atom feed in Java , i do this at regular intervals of 30 seconds, Based on the feed i must show a different UI.

I am not happy polling for feeds every 30 seconds, and would like to know if a better architecture exists to tackle this problem.

I dont think that I can get push notifications from the Feed Source or can I?

No you cannot. You can of course introduce a middle-layer component which will pull the feeds and then push them to your application but at the end of the day you would 'pull' anyway just to do the 'push'.

  • Thanks for your reply kris, So I am concluding that all Feed readers poll the subscribed websites at regular intervals , and if we want to listen to atom / rss feeds using Java then there's no other way than polling at regular intervals . – user1673160 Sep 17 '12 at 01:51
  • @user1673160 Not all feed readers are based just on polling. Some feeds do support push notifications, based on the pubsubhubbub specification: https://code.google.com/p/pubsubhubbub/, and some feed readers do exploit this capability. – Ivan Zuzak Sep 19 '12 at 20:11
  • Its an extension to Atom and Rss but thanks a lot for sharing, didn't know that smth like that exists. – Kris Sep 19 '12 at 21:23
  • @Kris Yeah, that's currently true, but the PSHB specification in its next version will not be tied to ATOM/RSS feeds -- it will be a generic pub-sub mechanism for the Web.
