Amazon Redshift Operators
=========================

`Amazon Redshift <https://aws.amazon.com/redshift/>`__ manages all the work of setting up, operating, and scaling a data warehouse:
provisioning capacity, monitoring and backing up the cluster, and applying patches and upgrades to
the Amazon Redshift engine. You can focus on using your data to acquire new insights for your
business and customers.

Airflow provides an operator to execute queries against an Amazon Redshift cluster.

Prerequisite Tasks
