title: Android Room insertAll issues
body: <p>I'm starting using Android Room and I'm having some troubles.</p>
  
  <p>I have an ArrayList of 7 Orders and when I call insertAll(List orders)
  only 4 orders are inserted into the database.</p>
  
  <p>How can I debug the insert query in order to find what is blocking ?</p>
  
  <p>Thanks</p>
