title: How to filter rows by length in Kettle
body: <p>I'm using a row filter to filter out columns that are longer than given length. Under filter conditions there are no conditions for checking row length.</p>
  
  <p>So the workaround is to use: </p>
  
  <pre><code>Field1 REGEXP [^.{0,80}$]
  OR
  Field1 IS NULL
  
  Field2 REGEXP [^.{0,120}$]
  OR
  Field2 IS NULL
  </code></pre>
  
  <p>Length check is a very common requirement. Is there a function/simpler way to do this that I'm missing?</p>
