.. py:class:: RedshiftClusterTrigger(task_id, polling_period_seconds, aws_conn_id, cluster_identifier, operation_type)

   Bases: :py:obj:`airflow.triggers.base.BaseTrigger`

   RedshiftClusterTrigger is fired as deferred class with params to run the task in trigger worker

   :param task_id: Reference to task id of the Dag
   :param polling_period_seconds:  polling period in seconds to check for the status
   :param aws_conn_id: Reference to AWS connection id for redshift
   :param cluster_identifier: unique identifier of a cluster
   :param operation_type: Reference to the type of operation need to be performed eg: pause_cluster, resume_cluster

   .. py:method:: serialize(self)

      Serializes RedshiftClusterTrigger arguments and classpath.


   .. py:method:: run(self)
      :async:

      Make async connection to redshift, based on the operation type call
      the RedshiftHookAsync functions
      if operation_type is 'resume_cluster' it will call the resume_cluster function in RedshiftHookAsync
      if operation_type is 'pause_cluster it will call the pause_cluster function in RedshiftHookAsync



.. py:class:: RedshiftClusterSensorTrigger(task_id, aws_conn_id, cluster_identifier, target_status, polling_period_seconds)

   Bases: :py:obj:`airflow.triggers.base.BaseTrigger`

   RedshiftClusterSensorTrigger is fired as deferred class with params to run the task in trigger worker

   :param task_id: Reference to task id of the Dag
   :param aws_conn_id: Reference to AWS connection id for redshift
   :param cluster_identifier: unique identifier of a cluster
   :param target_status: Reference to the status which needs to be checked
   :param polling_period_seconds:  polling period in seconds to check for the status

   .. py:method:: serialize(self)

      Serializes RedshiftClusterSensorTrigger arguments and classpath.


   .. py:method:: run(self)
      :async:

      Simple async function run until the cluster status match the target status.
