title: When should I use Greenplum Database versus HAWQ?
body: <p>We are having use case for retail industry data. We are into making of EDW.</p>
  
  <p>We are currently doing reporting from HAWQ.But We wanted to shift our MPP database from Hawq into Greenplum.
  Basically,We would like to make changes into current data pipeline.</p>
  
  <p><strong>Our confusion points about gpdb :</strong></p>
  
  <ul>
  <li>HOW gpdb layer going to affect  our existing data pipeline. Here data
  pipeline is external system --> talend -->hadoop-hawq-->tableau. We
  want to transform our data pipeline as external system --> talend
  -->hadoop-hawq-->greenplum -->tableau.</li>
  <li><p>How Greenplum is physically or logically going to help in SQL
  transformation and reporting.</p></li>
  <li><p>Which file format should i opt for storing the files in GPDB while<br>
  HAWQ we are storing  files in plain text format.What are the supported format is good for writing in gpdb like avro,parquet etc.</p></li>
  <li><p>How is data file processed from GPDB . so, that
  it also bring faster reporting and predictive analysis.</p></li>
  <li><p>Is there any way to push data  from  HAWQ into Greenplum?  We are<br>
  looking for guidance how to take shift our reporting use case from<br>
  HAWQ INTO Greenplum.</p></li>
  </ul>
  
  <p>Any help on it would be much appreciated?</p>
