.. py:class:: BatchOperator(*, job_name, job_definition, job_queue, overrides, array_properties = None, parameters = None, job_id = None, waiters = None, max_retries = None, status_retries = None, aws_conn_id = None, region_name = None, tags = None, **kwargs)

   Bases: :py:obj:`airflow.models.BaseOperator`

   Execute a job on AWS Batch

   .. seealso::
       For more information on how to use this operator, take a look at the guide:
       :ref:`howto/operator:BatchOperator`

   :param job_name: the name for the job that will run on AWS Batch (templated)

   :param job_definition: the job definition name on AWS Batch

   :param job_queue: the queue name on AWS Batch

   :param overrides: the `containerOverrides` parameter for boto3 (templated)

   :param array_properties: the `arrayProperties` parameter for boto3

   :param parameters: the `parameters` for boto3 (templated)

   :param job_id: the job ID, usually unknown (None) until the
       submit_job operation gets the jobId defined by AWS Batch

   :param waiters: an :py:class:`.BatchWaiters` object (see note below);
       if None, polling is used with max_retries and status_retries.

   :param max_retries: exponential back-off retries, 4200 = 48 hours;
       polling is only used when waiters is None

   :param status_retries: number of HTTP retries to get job status, 10;
       polling is only used when waiters is None

   :param aws_conn_id: connection id of AWS credentials / region name. If None,
       credential boto3 strategy will be used.

   :param region_name: region name to use in AWS Hook.
       Override the region_name in connection (if provided)

   :param tags: collection of tags to apply to the AWS Batch job submission
       if None, no tags are submitted

   .. note::
       Any custom waiters must return a waiter for these calls:
       .. code-block:: python

           waiter = waiters.get_waiter("JobExists")
           waiter = waiters.get_waiter("JobRunning")
           waiter = waiters.get_waiter("JobComplete")

   .. py:attribute:: ui_color
      :annotation: = #c3dae0

      
   .. py:attribute:: arn
      :annotation: :Optional[str]

      
   .. py:attribute:: template_fields
      :annotation: :Sequence[str] = ['job_name', 'overrides', 'parameters']

      
   .. py:attribute:: template_fields_renderers
      

   .. py:method:: execute(self, context)

      Submit and monitor an AWS Batch job

      :raises: AirflowException


   .. py:method:: on_kill(self)

      Override this method to cleanup subprocesses when a task instance
      gets killed. Any use of the threading, subprocess or multiprocessing
      module within an operator needs to be cleaned up or it will leave
      ghost processes behind.


   .. py:method:: submit_job(self, context)

      Submit an AWS Batch job

      :raises: AirflowException


   .. py:method:: monitor_job(self, context)

      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

      :raises: AirflowException


.. py:class:: AwsBatchOperator(*args, **kwargs)
