title: how to design a step for Spring batch that only do a read task
body: <p>My batch goes like Step1 Step2 and Step3( should be called if step2 is success).</p>
  
  <p>I need to do a count check using sql like select count(*) from table where condition = ? in step2.
  Fail if count is 0;</p>
  
  <p>As i have just a Read chunk and a Process check NOT a writer. but spring does not allow it. Should I try with tasklet ? 
  But tasklet is not a Reader ... Suggestion ? </p>
