title: Kubeflow, passing Python dataframe across components?
body: <p>I am writing a Kubeflow component which reads an input query and creates a <code>dataframe</code>, roughly as:</p>
  <pre><code>from kfp.v2.dsl import component 
  
  @component(...)
  def read_and_write():
      # read the input query 
      # transform to dataframe 
      sql.to_dataframe()
  </code></pre>
  <p>I was wondering how I can pass this dataframe to the next operation in my Kubeflow pipeline.
  Is this possible? Or do I have to save the dataframe in a csv or other formats and then pass the output path of this?
  Thank you</p>
