title: BigQuery reports for end users
body: <p>What is the recommended way to provide Bigquery access to end users?</p>
  
  <p>We have a multitenant application for appengine where each company has its own namespace in Datastore. We can ingest data from these individual namespaces into BigQuery and run various reports.</p>
  
  <p>We would like to let our users to be able to run queries in their respective BigQuery projects. What is the best way to achieve this? </p>
  
  <p>Possible options:</p>
  
  <ul>
  <li>user sends query to  appengine, which passes it to his BigQuery project and returns reply</li>
  <li>user sends query to BigQuery directly. The question here, how is the best to faciliate this?</li>
  <li>some other way?</li>
  </ul>
