title: JobExplorer spring batch and table prefix
body: <p>Is it really needed the table prefix of jobRepository tables to be changed for the jobExplorer bean?</p>
  
  <p>This is what the documentation says about it:</p>
  
  <blockquote>
    <p>Earlier in this chapter, it was mentioned that the table prefix of the
    JobRepository can be modified to allow for different versions or
    schemas. Because the JobExplorer is working with the same tables, it
    too needs the ability to set a prefix: 
  </blockquote>
  
  <p><code>class="org.spr...JobExplorerFactoryBean" p:dataSource-ref="dataSource" p:tablePrefix="BATCH_" /&gt;</code></p>
  
  <p>If the jobExplorer is only for reading purposes.. why should we have another set of jobRepository tables for that?</p>
