------------------------------------
[~feluelle]
there is download_file function in s3hook probably it just need to wrap it with
a new operator called S3DownloadOperator
> Add S3DownloadOperator
> ----------------------

> Key: AIRFLOW-2999
> URL: https://issues.apache.org/jira/browse/AIRFLOW-2999
> Project: Apache Airflow
> Issue Type: Task
> Affects Versions: 1.10.0
> Reporter: jack
> Priority: Major
>
> The [S3_hook
> |https://github.com/apache/incubator-airflow/blob/master/airflow/hooks/S3_hook.py#L177]
> has get_key method that returns boto3.s3.Object it also has load_file method
> which loads file from local file system to S3.
>
> What it doesn't have is a method to download a file from S3 to the local file
> system.
> Basicly it should be something very simple... an extention to the get_key
> method with parameter to the destination on local file system adding a code
> for taking the boto3.s3.Object and save it on the disk. Note: that it can be
> more than 1 file if the user choose a folder in S3.
>
> +*Update:*+
> As discussed in comments instead having the property in the hook it's better
> to mirror the GoogleCloudStorageDownloadOperator and have S3DownloadOperator
>
