title: Load DATE type to Google BigQuery with Dataflow
body: <p><strong>Context</strong></p>
  
  <p>I'm fairly new to the <strong>Google Cloud Platform</strong> and I'm trying out <strong>Google Dataflow</strong>. I read a CSV file and simulate streaming data. CSV row publishes into topic (PubSub) and <strong>Dataflow</strong> reads it and inserts the data into a BigQuery table.</p>
  
  <p><strong>Problem</strong></p>
  
  <p>When my file contains types STRING, FLOAT, INTEGER my process finished successfully and data is loaded to BigQuery. But if I add to my process one of those types: DATETIME, TIME, DATE it always fails. There are many code examples but I didn't find code example that show how to handle it.</p>
  
  <p><strong>Data Examples</strong></p>
  
  <p><code>2017-01-23</code> - load it into DATE type</p>
  
  <p><code>14:10:12</code> - load it into TIME type</p>
  
  <p>I hope you guys can help me with this ...</p>
