dbt-af is a tool that allows you to run dbt models in a distributed manner using Airflow. It acts as a wrapper around the Airflow DAG, allowing you to run the models independently while preserving their dependencies.

1. dbt-af is domain-driven. It is designed to separate models from different domains into different DAGs. This allows you to run models from different domains in parallel.
2. dbt-af brings scheduling to dbt. You can schedule your dbt models to run at a specific time.
3. dbt-af is an ETL-driven tool. You can separate your models into tiers or ETL stages and build graphs showing the dependencies between models within each tier or stage.
4. dbt-af brings additional features to use different dbt targets simultaneously, different tests scenarios, and maintenance tasks.

To install dbt-af run pip install dbt-af.

To contribute we recommend to use poetry to install package dependencies. Run poetry install --with=dev to install all dependencies.

All tutorials and examples are located in the examples folder.

To get basic Airflow DAGs for your dbt project, you need to put the following code into your dags folder:

# LABELS: dag, airflow (it's required for airflow dag-processor)
from dbt_af.dags import compile_dbt_af_dags
from dbt_af.conf import Config, DbtDefaultTargetsConfig, DbtProjectConfig

# specify here all settings for your dbt project
config = Config(
    dbt_project=DbtProjectConfig(
        dbt_project_name='my_dbt_project',
        dbt_project_path='/path/to/my_dbt_project',
        dbt_models_path='/path/to/my_dbt_project/models',
        dbt_profiles_path='/path/to/my_dbt_project',
        dbt_target_path='/path/to/my_dbt_project/target',
        dbt_log_path='/path/to/my_dbt_project/logs',
        dbt_schema='my_dbt_schema',
    ),
    dbt_default_targets=DbtDefaultTargetsConfig(default_target='dev'),
    is_dev=False,  # set to True if you want to turn on dry-run mode
)

dags = compile_dbt_af_dags(manifest_path='/path/to/my_dbt_project/target/manifest.json', config=config)
for dag_name, dag in dags.items():
    globals()[dag_name] = dag

In dbt_project.yml you need to set up default targets for all nodes in your project (see example):

sql_cluster: "dev"
daily_sql_cluster: "dev"
py_cluster: "dev"
bf_cluster: "dev"

This will create Airflow DAGs for your dbt project.
