About this task
The last step of the wizard shows the end schema generated and allows you to customize the schema according to your needs.
If needed, rename the schema (by default, metadata) and
leave a comment.
Customize the schema if needed: add, remove or move schema columns, export the schema to an XML file, or replace the schema by importing an schema definition XML file using the tool bar.Make sure the data type in the Type column is correctly defined.For more information regarding Java data types, including date pattern, see Java API Specification.Below are the commonly used Talend data types:
Object: a generic Talend data type that allows processing data without regard to its content, for example, a data file not otherwise supported can be processed with a tFileInputRaw component by specifying that it has a data type of Object.
List: a space-separated list of primitive type elements in an XML Schema definition, defined using the xsd:list element.
Document: a data type that allows processing an entire XML document without regarding to its content.
- If the JSON file which the schema is based on has been changed, click the Guess button to generate the schema again. Note that if you have customized the schema, the Guess feature does not retain these changes.
- Click Finish. The new file connection, along with its schema, is displayed under the relevant File Json metadata node in the Repository tree view.
