title: Should I use blob or text for JSON in MySQL?
body: <p>I am planning to store a <code>json_encoded</code> string on my database. I can't precisely tell the length its going to be, but I'm pretty sure it will be long. My concern is which field type I am going to use for this, is it <code>blob</code> or <code>text</code>?</p>
  
  <p>I prefer the one where I can save space as much as possible over fast searching, in any case I have other column where I should just index.</p>
