title: How Apache Storm parallelism works?
body: <p>I am new to Apache storm and wondering how parallelism hint works.</p>
  <p>For e.g. We have one stream containing two tuples &lt;4&gt;,&lt;6&gt;, one spout with only one task per executor and we have one bolt to perform some operation on the tuples and having parallelism hint as 2, so we have two executor of this bolt namely A and B, regarding this, I have 3 questions.</p>
  <ol>
  <li>Considering above scenario is this possible that our tuple which contain value 4 is processed by A and another tuple which contain value 6 is processed by B.</li>
  <li>If processing done in this manner i.e. mentioned in question (1), then won't it impact on operation in which sequence matter.</li>
  <li>If processing not done in this manner, means both tuples going to same executor then what is the benefit of parallelism.</li>
  </ol>
