title: Inserting from a huge table ( 1.8 billion records ) taking a lot of time in snowflake
body: <p>I am a beginner in snowflake and am trying benchmark a few queries with very high volume in snowflake. Currently my use-case is to insert a huge volume in a table.</p>
  <p>The syntax is :</p>
  <pre><code>Insert into tab1 ( cola,colb,colc ... colx) 
      Select ( cola,colb,colc ... colx) 
      from tab2;
  </code></pre>
  <p>The 1.8 billion row insert is taking around 16 minutes. Is there anything that I am doing wrong ?</p>
