Example: Using AWS Assume Role Authorization with READ_NOS - Teradata Vantage

Assume Role gives existing AWS IAM users and service accounts temporary access to AWS resources in other accounts.

1. Create the authorization object or have your administrator create it:

   CREATE AUTHORIZATION S3Invoker_auth
   AS INVOKER TRUSTED
   USING
   AUTHSERVICETYPE 'ASSUME_ROLE'
   ROLENAME 'role_name'
   EXTERNALID 'external_id';

   Where:

   role_name is the Amazon Resource Name (ARN) of the role to assume. For example: arn:aws:iam::844102931058:role/STSAssumeRole_TestRole.

   external_id is is the external ID which is assuming the role. For example: 3f68bc61-a455-4742-8039-8a03f0600db52.

2. Use READ_NOS to read data from an S3 CSV bucket. Note, the READ_NOS command is implicit in the following statement:

   SELECT * FROM (
     LOCATION = 'location'
     AUTHORIZATION = S3Invoker_auth) as dt;

   Where location is the bucket location. For example: /s3/s3.amazonaws.com/testuser1-sts-test/csv_default.csv.
