Classes

​
DbtCloudJobRun

Class that holds the information and methods to interact with the resulting run of a dbt Cloud job. Methods:

​
fetch_result 

fetch_result(self, step: Optional[int] = None) -> Dict[str, Any]
Gets the results from the job run. Since the results may not be ready, use wait_for_completion before calling this method. Args:
  • step: The index of the step in the run to query for artifacts. The first step in the run has the index 1. If the step parameter is omitted, then this method will return the artifacts compiled for the last step in the run.

​
get_run 

get_run(self) -> Dict[str, Any]
Makes a request to the dbt Cloud API to get the run data. Returns:
  • The run data.

​
get_run_artifacts 

get_run_artifacts(self, path: Literal['manifest.json', 'catalog.json', 'run_results.json'], step: Optional[int] = None) -> Union[Dict[str, Any], str]
Get an artifact generated for a completed run. Args:
  • path: The relative path to the run artifact.
  • step: The index of the step in the run to query for artifacts. The first step in the run has the index 1. If the step parameter is omitted, then this method will return the artifacts compiled for the last step in the run.
Returns:
  • The contents of the requested manifest. Returns a Dict if the requested artifact is a JSON file and a str otherwise.

​
get_status_code 

get_status_code(self) -> int
Makes a request to the dbt Cloud API to get the run status. Returns:
  • The run status code.

​
retry_failed_steps 

retry_failed_steps(self) -> 'DbtCloudJobRun'
Retries steps that did not complete successfully in a run. Returns:
  • A representation of the dbt Cloud job run.

​
wait_for_completion 

wait_for_completion(self) -> None
Waits for the job run to reach a terminal state.

​
