"""
This is an example dag for using `AWSDataSyncOperator` in a straightforward manner.

This DAG gets an AWS TaskArn for a specified source and destination, and then attempts to execute it.
It assumes there is a single task returned and does not do error checking (eg if multiple tasks were found).

This DAG relies on the following environment variables:

* SOURCE_LOCATION_URI - Source location URI, usually on premises SMB or NFS
* DESTINATION_LOCATION_URI - Destination location URI, usually S3
