title: Automatic job to delete bigquery table records
body: <p>Is there a way to schedule deletion of rows from bigquery table based on a column condition? Something like a job to schedule to run every day.</p>
  <p>For example, let's say I've a column called creation_date in the table. I need to delete records when creation_date is less than current date minus one week (<code>creation_date &lt; current date - 7</code>). I need the job to run everyday on a specified time and delete records based on the creation date condition.</p>
  <p>If there aren't any built in scheduler operations, could you suggest any options available?</p>
