title: GROUP EACH BY limit
body: <p>I have a huge table with 20,235,447,221 rows clocked in at 1.32 TB. I need to find the unique rows and count them so I use the GROUP EACH BY to accomplish that.</p>
  
  <p>However, I get the Error: Resources exceeded during query execution error.</p>
  
  <p>Is there anyway to execute the table without running out resources? If not, how do I find the ceiling of the number of rows a table can have for this to succeed?</p>
  
  <p>Thank you.</p>
