title: Multithreaded processing of data with spring batch
body: <p>I am looking for a help with simple (I think so) problem with spring batch. My task is to read list of transactions from database, group them by account number and order by date and later on do some processing for set of transactions for specific account number.Once I read data and group them by account number I can process these chunks in parallel. Every such operations will update account balance. I am new to spring batch and looking for example of spring configuration. Can you help me?</p>
