Calculate the exponential backoff (in seconds) until the next attempt. |
|
Retry a callable function with exponential backoff between attempts if it raises an exception. |
Attributes¶
- airflow.providers.amazon.aws.executors.utils.exponential_backoff_retry.calculate_next_attempt_delay(attempt_number, max_delay=60 * 2, exponent_base=4)[source]¶
Calculate the exponential backoff (in seconds) until the next attempt.
- airflow.providers.amazon.aws.executors.utils.exponential_backoff_retry.exponential_backoff_retry(last_attempt_time, attempts_since_last_successful, callable_function, max_delay=60 * 2, max_attempts=-1, exponent_base=4)[source]¶
Retry a callable function with exponential backoff between attempts if it raises an exception.
- Parameters
last_attempt_time (datetime.datetime) – Timestamp of last attempt call.
attempts_since_last_successful (int) – Number of attempts since last success.
callable_function (Callable) – Callable function that will be called if enough time has passed.
max_delay (int) – Maximum delay in seconds between retries. Default 120.
max_attempts (int) – Maximum number of attempts before giving up. Default -1 (no limit).
exponent_base (int) – Exponent base to calculate delay. Default 4.
