title: Location and UseCase for AggregateItemReader
body: <p><a href="http://docs.spring.io/spring-batch/trunk/reference/html/listOfReadersAndWriters.html" rel="nofollow">Appendix Here</a> lists a reader <code>AggregateItemReader</code> but I am not able to find it in any of Spring Batch jar files. I am using spring batch with spring boot and have version 3.0.7.</p>
  
  <p><a href="http://docs.spring.io/spring-batch/apidocs/org/springframework/batch/sample/domain/multiline/AggregateItemReader.html" rel="nofollow">API Doc</a> indicates it in samples package. </p>
  
  <p>Currently, I am using <code>JdbcPagingItemReader</code> in my project but I want reader to return a <code>List</code> or <code>Collection</code> of objects to processor instead of a single object.This is needed so I can process those objects in bulk instead of processing one by one. </p>
  
  <p>Pagination requirement is mandatory so I use <code>JdbcPagingItemReader</code></p>
  
  <p>By reading description, it looks <code>AggregateItemReader</code> was the candidate but can't find its implementation. </p>
  
  <p>Any Ideas? Are there any alternatives?</p>
