tSQSQueuePurge Standard properties

Use an existing connection

Select this check box and in the Component List drop-down list, select the desired connection component to reuse the connection details you already defined.

Credential provider

Specify the way to obtain AWS security credentials: Static Credentials, Inherit credentials from AWS role, or Provider credentials or inherit from AWS role.

• Static Credentials: Use access key and secret key as the AWS security credentials.
• Inherit credentials from AWS role: Obtain AWS security credentials from your EMR instance metadata. To use this option, the Amazon EMR cluster must be started and your Job must be running on this cluster. For more information, see Using an IAM Role to Grant Permissions to Applications Running on Amazon EC2 Instances. This option enables you to develop your Job without having to put any AWS keys in the Job, thus easily comply with the security policy of your organization.
• Provider credentials or inherit from AWS role: Obtain AWS security credentials from provider credentials or from your EMR instance metadata. You can specify the profile configuration file in the Profile config file path field and specify the profile in the Profile name field.

Access Key and Secret Key

Specify the access keys (the access key ID in the Access Key field and the secret access key in the Secret Key field) required to access the Amazon Web Services. For more information on AWS access keys, see Access keys (access key ID and secret access key).

To enter the secret key, click the [...] button next to the secret key field, and then in the pop-up dialog box enter the password between double quotes and click OK to save the settings.

These two fields are available when Static Credentials is selected from the Credential Provider drop-down list.

Assume Role

If you temporarily need some access permissions associated to an AWS IAM role that is not granted to your user account, select this check box to assume that role. Then specify the values for the following parameters to create a new assumed role session.

Ensure that access to this role has been granted to your user account by the trust policy associated to this role. If you are not certain about this, ask the owner of this role or your AWS administrator.

Region

Specify the AWS region by selecting a region name from the list or entering a region between double quotation marks (for example "us-east-1") in the list. For more information on AWS Regions, see AWS Regions and Endpoints.

Queue (Name or URL)

Specify the name or the URL of the queue in which messages will be purged.

Die on error

Select the check box to stop the execution of the Job when an error occurs.

Clear the check box to skip any error and continue the Job execution process.

Config client

STS Endpoint

Select this check box to specify the AWS Security Token Service (STS) endpoint from which to retrieve the session credentials. For example, enter sts.amazonaws.com.

This service allows you to request temporary, limited-privilege credentials for the AWS user authentication. Therefore, you still need to provide the access key and secret key to authenticate the AWS account to be used.

For a list of the STS endpoints you can use, see AWS Security Token Service. For further information about the STS temporary credentials, see Temporary Security Credentials. Both articles are from the AWS documentation.

This check box is available only when the Assume Role check box is selected.

Select the AWS region of the STS service. If the region is not in the list, you can enter its name between double quotation marks. The default value is us-east-1.

This drop-down list is available only when the Assume Role check box is selected.

If the administrator of the account to which the role belongs provided you with an external ID, enter its value here. The External Id is a unique identifier that allows a limited set of users to assume the role.

This field is available only when the Assume Role check box is selected.

When you assume a role, the trust policy of this role might require Multi-Factor Authentication (MFA). In this case, you must indicate the identification number of the hardware or virtual MFA device that is associated with the user who assumes the role.

This field is available only when the Assume Role check box is selected.

When you assume a role, the trust policy of this role might require Multi-Factor Authentication (MFA). In this case, you must indicate a token code. This token code is a time-based one-time password produced by the MFA device.

This field is available only when the Assume Role check box is selected.

List session tags in the form of key-value pairs. You can then use these session tags in policies to allow or deny access to requests.

Transitive: select this check box to indicate that a tag will persist to the next role in a role chain.

For more information about tags, see Passing Session Tags in AWS STS

This field is available only when the Assume Role check box is selected.

Enter the Amazon Resource Names (ARNs) of the IAM managed policies that you want to use as managed session policies. Use managed session policies to limit the permissions of the session. The policies must exist in the same account as the role. The resulting session's permissions are the intersection of the role's identity-based policy and the session policies.

For more information about session policies, see the corresponding section in Policies and Permissions

This field is available only when the Assume Role check box is selected.

Enter an IAM policy in JSON format that you want to use as a session policy. Use session policies to limit the permissions of the session. The resulting session's permissions are the intersection of the role's identity-based policy and the session policies.

For more information about session policies, see the corresponding section in Policies and Permissions

This field is available only when the Assume Role check box is selected.

tStatCatcher Statistics

Select this check box to gather the Job processing metadata at the Job level as well as at each component level.

ERROR_MESSAGE

The error message generated by the component when an error occurs. This is an After variable and it returns a string. This variable functions only if the Die on error check box is selected.

Usage rule

This component can be used as a standalone component of a Job or subJob.
