Authentication Methods

Password-based authentication

      connect_timeout: 10 # default 10 seconds
      # search_path: public # optional, not recommended
      sslmode: [optional, set the sslmode used to connect to the database (in case this parameter is set, will look for ca in ~/.postgresql/root.crt)]
      ra3: true # enables cross-database sources

IAM Authentication

To set up a Redshift profile using IAM Authentication, set the method parameter to iam as shown below. Note that a password is not required when using IAM Authentication. For more information on this type of authentication, consult the Redshift Documentation and boto3 docs on generating user credentials with IAM Auth.

If you receive the "You must specify a region" error when using IAM Authentication, then your aws credentials are likely misconfigured. Try running aws configure to set up AWS access keys, and pick a default region. If you have any questions, please refer to the official AWS documentation on Configuration and credential file settings.

Specifying an IAM Profile

New in dbt v0.18.0

The iam_profile config option for Redshift profiles is new in dbt v0.18.0

When the iam_profile configuration is set, dbt will use the specified profile from your ~/.aws/config file instead of using the profile name default

Redshift notes

Where possible, dbt enables the use of sort and dist keys. See the section on Redshift specific configurations.
