title: What is the maximum number of nested records in a record?
body: <p>If I create a record in BigQuery how many different nested records can I have inside in the schema? Is there a limit to the size of the schema?
  Is this possible:
  AA: Record
    A1: Record
    A2: Record
    ....
    A1000: Record</p>
  
  <p>Note, I understand there is an option to have A be a repeated record, I am not interested\not asking about this option.</p>
  
  <p>Thanks</p>
