title: Is there a standard naming convention for keysets, column families, and column names
body: <p>I am new to this technology, I have a hard time to find answer to this basic question.
  Is there widely adopted naming convention for keysets, column families and column names,
  such as</p>
  
  <ul>
  <li>PascalCase</li>
  <li>camelCase</li>
  <li>snake_case</li>
  <li>alllowercase</li>
  </ul>
  
  <p>Project I am looking at is using alllowercase, so I am wondering if there is a reason behind it.</p>
