title: Oracle (RAC) vs NoSQL
body: <p>I am curious if anybody did benchmarks for accessing of data in NoSQL databases vs Oracle (particularly I am talking about Oracle RAC)?
  The project requires to work with at least 10mil+ of records, search among them (but not necessary have to be real time), the <em>read</em> is very important for speed, and it's also very important to guarantee HA and reliability (can't lose records!!!)
  I can see for myself how say Cassandra/MongoDB might be better fit (because key value storage will provide faster reads than SQL when you go over 10mil records), but I find difficult to articulate all of them nicely. Any links? Suggestions? Bullet points?
  Thanks!</p>
