[aerogear-dev] Feedback for aerogear-unifiedpush-server - personalized push notifications case

[Karel Piwko]

I think that Coarse Grained way might need some batch support or to be pretty
specific about limits, e.g. max 1000 messages per HTTP request in documetation.

Additionally, from what I've experienced, making Fine Grained access run in
parallel depletes server's pool of concurrent sessions pretty quickly, so
Coarse Grained might be a performance optimalization as well.
