Configure an Amazon Redshift Bulk Connection

To use the bulk connection via the Output Data tool:

Click the Write to File or Database drop-down and select Other Databases > Amazon Redshift Bulk.
Select a Data Source Name (or click ODBC Admin to create one). See ODBC and OLEDB Database Connections.
(Optional) Type a User Name and Password.
In the Amazon S3 section, type or paste your AWS Access Key and AWS Secret Key to access the data for upload.
In the Secret Key Encryption drop-down, select an encryption option:

Hide: Hide the password using minimal encryption.
Encrypt for Machine: Any user on the computer will be able to fully use the connection.
Encrypt for User: The logged in user can use the connection on any computer.

In the Endpoint drop-down, select Default to allow Amazon to determine the endpoint automatically based on the bucket you select. To specify an endpoint for private S3 deployments, or if you know a specific bucket region, you can alternately select an endpoint (S3 region), enter a custom endpoint, or select from one of ten previously-entered custom endpoints.

If the Bucket you select is not in the region of the endpoint you specify, the following error occurs: “The bucket you are attempting to access must be addressed using the specified endpoint. Please send all future requests to this endpoint.” Select Default to clear the error.

(Optional) Select Use Signature V4 for Authentication to use Signature Version 4 instead of the default Signature Version 2. This will increase security, but connection speeds may be slower. This option is automatically enabled for regions requiring Signature Version 4.
