If, for example, we need to run hourly-tagged models every hour and daily-tagged models daily, we can create jobs like `Hourly Run` or `Daily Run` and utilize the commands `dbt run -s tag:hourly` and `dbt run -s tag:daily` within each, respectively. We only need to grab our dbt Cloud `account` and `job id`, configure it in an Airflow DAG with the code provided, and then we can be on your way. See more node selection options: [here](/reference/node-selection/syntax) - -### How can I re-run models from the point of failure? - -You may want to parse the dbt DAG in Airflow to get the benefit of re-running from the point of failure. However, when you have hundreds of models in your DAG expanded out, it becomes useless for diagnosis and rerunning due to the overhead that comes along with creating an expansive Airflow DAG. +Because the Airflow DAG references dbt Cloud jobs, your analytics engineers can take responsibility for configuring the jobs in dbt Cloud. -You can’t re-run from failure natively in dbt Cloud today (feature coming!), but you can use a custom rerun parser. +For example, to run some models hourly and others daily, there will be jobs like `Hourly Run` or `Daily Run` using the commands `dbt run --select tag:hourly` and `dbt run --select tag:daily` respectively.

Refer to our full [node selection syntax docs here](/reference/node-selection/syntax). -Using a simple python script coupled with the dbt Cloud provider, you can: - -- Avoid managing artifacts in a separate storage bucket(dbt Cloud does this for you) -- Avoid building your own parsing logic -- Get clear logs on what models you're rerunning in dbt Cloud (without hard coding step override commands) - -Watch the video below to see how it works! +### How can I re-run models from the point of failure? - +You can trigger re-run from point of failure with the `rerun` API endpoint. See the docs on [retrying jobs](/docs/deploy/retry-jobs) for more information. ### Should Airflow run one big dbt job or many dbt jobs? -Overall we recommend being as purposeful and minimalistic as you can. This is because dbt manages all of the dependencies between models and the orchestration of running those dependencies in order, which in turn has benefits in terms of warehouse processing efforts. +dbt jobs are most effective when a build command contains as many models at once as is practical. This is because dbt manages the dependencies between models and coordinates running them in order, which ensures that your jobs can run in a highly parallelized fashion. It also streamlines the debugging process when a model fails and enables re-run from point of failure. + +As an explicit example, it's not recommended to have a dbt job for every single node in your DAG.

Specifically, if your python model is incremental, the current execution pattern involves executing python to create a staging table that is then merged into your target table using SQL. The python code needs to run on an all purpose cluster, while the SQL code can run on an all purpose cluster or a SQL Warehouse.
