Advanced Amazon S3 Options

When the Amazon S3 file method is selected, these additional advanced options may be set:

Item	Name	Default Value	Description
A	Use Default Credential Provider Chain	Yes	If enabled and no explicit credentials are provided, the default provider chain looks for credentials in this order: Environment variables: AWS_ACCESS_KEY_ID and AWS_SECRET_ACCESS_KEY Java system properties: aws.accessKeyId and aws.secretKey Default credentials profile file: Typically located at ~/.aws/credentials (location can very per platform) ECS container credentials: Loaded from an Amazon ECS environment variable. Instance profile credentials: Loaded from the EC2 metadata service. Note that if your File Reader has Anonymous enabled, this option will not be enabled.
B	Use Temporary Credentials	No	If enabled, the given credentials will be used to request a set of temporary credentials from the Amazon Security Token Service (STS). Those temporary credentials will then be used for all S3 operations.
C	Duration (seconds)	7200	The duration that the temporary credentials are valid. Must be between 900 seconds (15 minutes) and 129,600 seconds (36 hours).
D	Region	us-west-2	The AWS region that your S3 bucket is located in. Select a specific region from the drop-down menu, or enter one into the text field. You can also use Velocity Variable Replacement here.
E	Custom HTTP Headers	pollId	These headers will be used on any S3 PUT operation. They are not used for GET operations. To add user-defined metadata tags to the S3 object, include a custom header that starts with "x-amz-meta-". For more information, check out the official Amazon S3 documentation.
