What is the function of the `--models` flag in dbt commands?

The function of the --models flag in dbt commands is to specify which models to run, test, or debug. This allows users to target specific models within a dbt project, enabling a more focused approach to running dbt operations rather than executing all available models. By defining a subset of models, an analyst can efficiently conduct tests, run specific transformations, or troubleshoot particular models without affecting the entire project.

This targeted execution is especially useful in larger projects where running all models may be time-consuming and unnecessary when only a few need attention. It enhances workflow efficiency and tailors the command execution to the user's immediate needs.

The other options presented, while they touch on important aspects of dbt functionality, do not accurately describe the purpose of the --models flag. The flag does not compile all models, disable model execution, or load models from external sources, maintaining a focused function on model specification for dbt operations.
