  • max_retries (Optional[int]) -- exponential back-off retries, 4200 = 48 hours; polling is only used when waiters is None

  • status_retries (Optional[int]) -- number of HTTP retries to get job status, 10; polling is only used when waiters is None

monitor_job(self, context)[source]

Monitor an AWS Batch job monitor_job can raise an exception or an AirflowTaskTimeout can be raised if execution_timeout is given while creating the task. These exceptions should be handled in taskinstance.py instead of here like it was previously done
