The batch job builds record blocks of the configured block size and sends them to their corresponding batch step for processing. Each batch stepreceives one or more record blocks and starts processing them in parallel. After the batch step processes a record, the batch step sends the record to the aggregator for further processing. The aggregator continues processing records until the number of aggregated records reaches the configured aggregator’s size.
