title: Max length of varchar / text in cassandra
body: <p>I am trying to find the answer to a simple question.
  Let say I have a table which I store content in it.
  The content is just a string.
  I am trying to find what is my max length for this specific one?
  I was reading that "text" type is just an alias to varchar. Is varchar length only 255 or it can be more?</p>
