Ruby on Rails and NoSQL Databases

Rails
1

Hi,

I have some questions regarding RoR & NoSQL Databases…

  1. How viable is the use of a NoSQL DB w/ RoR?

  2. How common is it (e.g. are people building “big apps” in this
    paradigm, yet)?

  3. Where can I find solid resources that help understand how to use
    NoSQL DBs w/ RoR?

  4. Has anyone successfully used RoR w/ NoSQL DBs on Mac and, if so,
    where can I find reading material on the topic?

Thanks, in advance, for your help. I appreciate it!
