    Description

      Implement a JpaItemReader to read batch data from db via Java Persistence API (version 2.1).

      It should support pagination by using javax.persistence.Query#setFirstResult and javax.persistence.Query#setMaxResults. For very large amount of data, we don't want to load them all into memory in one query run.
