Re: [aerogear-dev] [simplepush] Performance

The concern with using Mongo is that it's very lossy and fairly unreliable as a data store for a number of reasons. (It's fine for simple, low demand systems, but has complications once you really start to hammer on it.) http://blog.schmichael.com/2011/11/05/failing-with-mongodb/ http://blog.engineering.kiip.me/post/20988881092/a-year-with-mongodb etc. I'd suggest sticking with other DBs unless you're ok with loss or don't plan on heavily exercising it.
