Cúram batch processes can also avail of transaction level data caching. Utilization of this mechanism can greatly reduce the volume of database I/O required for batch process execution. A good example of the performance savings that this provides is when an error is encountered when processing a record, requiring it to be skipped or excluded. Caching of data in such situations (where processing effectively needs to restart without including a particular record) greatly improves operational efficiency.
Chapter 3 provides a description of the caches available to Cúram batch process developers.
