title: dask DataFrame equivalent of pandas DataFrame sort_values
body: <p>What would be the equivalent of sort_values in pandas for a dask DataFrame ? I am trying to scale some Pandas code which has memory issues to use a dask DataFrame instead.</p>
  
  <p>Would the equivalent be :</p>
  
  <pre><code>ddf.set_index([col1, col2], sorted=True)
  </code></pre>
  
  <p>?</p>
