Redshift

Preparation

To allow Shaped to connect to your Redshift data warehouse, you need to create a read-only user and share its credentials through the Create Model request. You can create this user with the following steps on your Redshift cluster:

# 1. Create a new user.
CREATE USER read_only_user WITH PASSWORD 'secure_password1!';

# 2. Create a group for granting/revoking permissions.
CREATE GROUP read_only_group;

# 3. Add user to group.
ALTER GROUP read_only_group ADD USER read_only_user;

# 4. Revoke default granted create rights in schema from group.
REVOKE CREATE ON SCHEMA public FROM GROUP read_only_group;

# 5. Grant the group usage access to the schema.
GRANT USAGE ON SCHEMA public TO group read_only_group;

# 6. Grant the group read access to all the tables in the schema. Note you can also 
# restrict this to your specific user, item and interaction views.
GRANT SELECT ON ALL TABLES IN SCHEMA public TO group read_only_group;

# 7. Grant the group access to future tables in the schema.
ALTER DEFAULT PRIVILEGES IN SCHEMA public GRANT SELECT ON TABLES TO group read_only_group;

You’ll also need to create an associated IAM role for Shaped to access your Redshift cluster and staging location.
