Customize the data load utility
The data load utility is based on an extensible infrastructure, which can be customized to meet specific business needs.
- Create custom data readers
Create a custom data reader to load data from a source that is not in CSV file format, which is the default data source format of the data load utility. It is not necessary to change the format of the existing data to work with the data load utility.
