Using redshift-data boto3 to make cross account redshift calls

Question

HI

I am using Boto3 - redshift-data to connect/query to Redshift.

I would like to connect to a redshift cluster in a different account. Where do I set the account id or URL for cross account Redshift query ?

Currently I am doing:

```
redshift_client_data = boto3.client('redshift-data')
test_query = redshift_client_data.execute_statement(
        ClusterIdentifier='rs-****-d1',
        Database='dw1',
        DbUser='username',

Sql='select * from ***.address_data limit 35;',

)

```

How do we modify clusterIdentifier to do cross account calls  ?
Thanks

Answer

You can/should specify and API KEY & ID when you're constructing your client which refers to an identity in the target account.

```
redshift_client = boto3.client('redshift-data',
            aws_access_key_id='abc',
            aws_secret_access_key='123'
        )
```

Answer

See https://docs.aws.amazon.com/redshift/latest/mgmt/data-api.html :
"To run a query on a cluster that is owned by another account, the owning account must provide an IAM role that the Data API can assume in the calling account."
