I want to invoke execute_statement API of Redshift Serverless with a create user statement like CREATE USER "john" PASSWORD 'johnDoe1';. However, when I do this via Python script (or AWSCustomResource in CDK), I get

must be superuser or have CREATE USER system privilege to create users

And when I try to use my admin credentials by using DbUser like below, I get

DB User cannot be set during a serverless request.`

response = client.execute_statement(
        WorkgroupName='emr-workgroup',
        Database='dev',
        DbUser='admin',
        Sql=sql
    )

How can I automate this without having to go manually to the query console and execute these queries? How an IAM role can be a superuser so that I can execute such queries in an automated way?

  • hey @shiva did you get anywhere with this? I'd love to use CDK to create users/groups in Redshift Serverless, but there don't seem to be any constructs to do so.... only for Redshift standard: constructs.dev/packages/@aws-cdk/aws-redshift-alpha/v/… Commented Nov 26 at 6:48
  • Sadly this is not possible currently so I had to do this manually Commented Nov 26 at 17:04
