Parameters

  • query (str) – Trino/Presto query to be run on Amazon Athena. (templated)

  • database (str) – Database to select. (templated)

  • catalog (str) – Catalog to select. (templated)

  • output_location (str | None) – s3 path to write the query results into. (templated) To run the query, you must specify the query results location using one of the ways: either for individual queries using either this setting (client-side), or in the workgroup, using WorkGroupConfiguration. If none of them is set, Athena issues an error that no output location is provided

  • client_request_token (str | None) – Unique token created by user to avoid multiple executions of same query

  • workgroup (str) – Athena workgroup in which query will be run. (templated)

  • query_execution_context (dict[str, str] | None) – Context in which query need to be run

  • result_configuration (dict[str, Any] | None) – Dict with path to store results in and config related to encryption

  • sleep_time (int) – Time (in seconds) to wait between two consecutive calls to check query status on Athena

  • max_polling_attempts (int | None) – Number of times to poll for query state before function exits To limit task execution time, use execution_timeout.

  • log_query (bool) – Whether to log athena query and other execution params when it’s executed. Defaults to True.

  • aws_conn_id – The Airflow connection used for AWS credentials. If this is None or empty then the default boto3 behaviour is used. If running Airflow in a distributed manner and aws_conn_id is None or empty, then default boto3 configuration would be used (and must be maintained on each worker node).

  • region_name – AWS region_name. If not specified then the default boto3 behaviour is used.

  • verify – Whether or not to verify SSL certificates. See: https://boto3.amazonaws.com/v1/documentation/api/latest/reference/core/session.html

  • botocore_config – Configuration dictionary (key-values) for botocore client. See: https://botocore.amazonaws.com/v1/documentation/api/latest/reference/config.html
