title: Google Dataflow vs Apache Spark
body: <p>I am surveying <strong>Google Dataflow</strong> and <strong>Apache Spark</strong> to decide which one is more suitable solution for our bigdata analysis business needs.</p>
  
  <p>I found there are <code>Spark SQL</code> and <code>MLlib</code> in the spark platform to do structured data query and machine learning. </p>
  
  <p>I wonder is there any corresponding solution in the Google Dataflow platform?</p>
