Understanding metadata in Talend Studio
Talend Studio allows you to create and run Jobs using predefined components. You can configure each component as either a Built-in or a Repository component. A Repository component is saved as metadata.
For Built-in components, information (such as how to
read the file and what it contains):
- is defined in the component,
- applies only to this component,
- cannot be reused with any other component.
For Repository components, information (such as how to
read the file and what it contains):
- is saved as metadata,
- can be efficiently and consistently reused,
- can be easily maintained because changes to metadata can be propagated to all Jobs that use it.
