Maybe I am biased with DBpedia but by doing some

Wikipedia we found that the ideal update with OAI-PMH time was every ~5
minutes.
OAI aggregates multiple revisions of a page to a
single edit
so when we ask: "get me the items that changed the last 5 minutes" we skip the
processing of many minor edits
It looks like we lose this option with PubSubHubbub right?
I'm not quite positive on this point, but I think with PuSH, this is done by the
hub. If the hub gets 20 notifications for the same resource in one minute, it
will only grab and distribute the latest version, not all 20.
But perhaps someone from the PuSH development team could confirm this.
It 'd be great if the dev team can confirm this.
Besides push notifications, is polling an option in PuSH? I briefed through the
spec but couldn't find this.
Yes. You can just poll the interface that the hub uses to fetch new data.
