Parameters for the Crossref Metadata Telescope

Parameters:
  • dag_id – the id of the DAG.

  • cloud_workspace – the cloud workspace settings.

  • bq_dataset_id – the BigQuery dataset id.

  • bq_table_name – the BigQuery table name.

  • api_dataset_id – the Dataset ID to use when storing releases.

  • schema_folder – the SQL schema path.

  • dataset_description – description for the BigQuery dataset.

  • table_description – description for the BigQuery table.

  • crossref_metadata_conn_id – the Crossref Metadata Airflow connection key.

  • crossref_base_url – The crossref metadata api base url.

  • observatory_api_conn_id – the Observatory API connection key.

  • max_processes – Max number of parallel processes. If None, will be determined at task runtime with cpu count.

  • batch_size – the number of files to send to ProcessPoolExecutor at one time.

  • start_date – the start date of the DAG.

  • schedule – the schedule interval of the DAG.

  • catchup – whether to catchup the DAG or not.

  • max_active_runs – the maximum number of DAG runs that can be run at once.

  • retries – the number of times to retry a task.

  • test_run – Whether this is a test run or not.

  • gke_namespace – The cluster namespace to use.

  • gke_volume_name – The name of the persistent volume to create

  • gke_volume_size – The amount of storage to request for the persistent volume

  • kwargs – Takes kwargs for building a GkeParams object.
