spark-challenges's Issues

Question on challenge

Thank you for the example. Learned quite a bit! I have following questions if you can help!

  1. Why do we have to sort the department DF? What advantage does it give?
  2. Why to sort in this specific order: 'id, 'assigned_date, 'company_id, 'factory_id' ?
  3. What is the intent of the query in the code? Count of all users whose joined a department on the same day their birth date?
