Validate is a processor function that operates on data as it passes through a stream. Rules can be configured on data fields in the user interface displayed in the Rules tab or written in JSON file format in the Schema tab. Most rules can be set up in the Rules tab, which automatically generates a JSON schema. For rules that cannot be created using the user interface, you can define them directly in the Schema tab.
