Amazon Simple Notification Service (SNS) Operators
==================================================

`Amazon Simple Notification Service (Amazon SNS) <https://aws.amazon.com/sns/>`__  is a managed
service that provides message delivery from publishers to subscribers (also known as producers
and consumers). Publishers communicate asynchronously with subscribers by sending messages to
a topic, which is a logical access point and communication channel. Clients can subscribe to the
SNS topic and receive published messages using a supported endpoint type, such as Amazon Kinesis
Data Firehose, Amazon SQS, AWS Lambda, HTTP, email, mobile push notifications, and mobile text
messages (SMS).

Airflow provides an operator to publish messages to an SNS Topic.
