title: Not expected "Requests too large" exception in gremlin query [azure-cosmosdb]
body: <p>We were experiencing some issues with RequestRateTooLargeException  .
  I would like to get some insights.</p>
  
  <p>If I tried to run this I get the Exception:</p>
  
  <pre><code>g.V('e078e211-460c-4b18-bf03-e68313dabdcc').as('u').V('0b30599f-ae5b-4cde-9fb3-06c44d54d792').inE('follows').where(outV().as('u'))
  </code></pre>
  
  <p>Should not be this a very simple query?
  This particular vertex has a lot of "Follow" edges.
  If I try with a different vertex with only a few "Follow" edges the query consumes 11RUs.
  The indexes are the default ones.</p>

  <p>Thanks in advance
