title: Ho can I store big quantity of data?
body: <p>I have to store packages of data retrieved from n machines every 10 seconds. These informations have to been saved into a db and stay here forever. Furthermore, data package has to be flexible (if tomorrow I want to add a new data I have to can do it).
  First idea i have thougth is to save each machine package of data in a log file into a sql table but in short time I'd have enormous files hard to be read or written by a nodejs aplication. Also I'd need more space into db.
  Is there a way to store big quantity of data and mantain high performance? I know nothing about big data storage but can it be the solution?</p>
