title: How Cassandra file system interacts with platform file system
body: <p>I am doing research regarding NoSql. I have found two DBs that are close to what I require for implementation. </p>
  
  <p>just wondering how the file system of these Nosql interacts with Windows/Linux file system?</p>
  
  <p>for instance, Cassandra uses Cassandra file system, so is it the case that it is a virtual file system that with help of JRE/JDK, it interacts with the platform file system?</p>
