title: BigQuery - Query planning used too many resources - What to do?
body: <p>I have a medium complicated query with only some 60 rows and 4 joins of maximum 1M rows tables. However the query does not run and returns the following error:</p>
  
  <blockquote>
    <p><strong>Error:</strong> Query planning used too many resources</p>
  </blockquote>
  
  <p>Is there a simple way to solve it? I only use <code>JOIN EACH</code> and <code>GROUP EACH BY</code> but it does not help. (This was suggested in a similar question <a href="https://stackoverflow.com/questions/43636268/bigquery-resources-exceeded-with-huge-query">here</a>)</p>
  
  <p>In addition, yesterday the query ran and returned results but since this morning there is this error.</p>
