What does the '*' operator do in graph operators?

The '' operator in graph operators is used to match all models within a specified package or directory. This feature is beneficial when you want to include a comprehensive set of models without having to list each one individually. By employing the '' operator, you can leverage the power of graph-based selection to maintain a clean and efficient workflow, especially when your project contains multiple models with interconnected dependencies.

Using this operator promotes flexibility and scalability in your analytics workflow, allowing you to easily encompass changes in your model structure. For instance, if new models are added to a directory, they will automatically be included in the selection process, thus streamlining the development process and reducing manual updates.

The other choices do not accurately describe the function of the '' operator. Some options suggest functionalities related to model dependencies or field selection, which are distinct aspects of managing dbt projects but not applicable to the use of the '' operator in this context.
