title: Why Azure Data Factory when we have Polybase
body: <p>Our requirement is to take data from Blob Storage and convert to other tabular form. This can be achieved with Sql DW using polybase. What really is the role of Azure data factory in such cases? </p>
  
  <p>I know the same objective can be met with Azure data factory. But isn't Azure DW with Polybase the easiest option and cost effective? </p>
