# Connect Redshift

[Data warehouse requirements](/data-requirements/warehouse-requirements.md)

1. Connect to your **Redshift Cluster**
2. Execute the following SQL. These commands create a roadway user and grant read and write permissions to the tables (view [Data warehouse requirements](/data-requirements/warehouse-requirements.md)) required by Roadway. Make sure to change the placeholders for the correct database and schema Roadway should use; we do not need access to your entire data warehouse.

```sql
CREATE USER roadway_user PASSWORD <'your_strong_password'>;

GRANT USAGE ON SCHEMA <your_database_name>.<your_schema_name> TO roadway_user;
GRANT CREATE ON SCHEMA <your_database_name>.<your_schema_name> TO roadway_user;
GRANT SELECT, INSERT ON ALL TABLES IN SCHEMA <your_database_name>.<your_schema_name> TO roadway_user;
ALTER DEFAULT PRIVILEGES FOR USER <your_internal_management_user> IN SCHEMA <your_database_name>.<your_schema_name>
GRANT SELECT ON TABLES TO roadway_user;
```

Next you need to Configure Network Accessibility (Using AWS Management Console)

1. Go to AWS Management Console > Redshift and select your cluster
2. Make sure the cluster security settings allow for inbound connections. For this, you can follow [this AWS Tutorial](https://docs.aws.amazon.com/redshift/latest/mgmt/rs-security-group-public-private.html).

Afterwards, share connection credentials with Roadway:

* cluster name / endpoint, e.g. `example_cluster.<account_id>.<your-cluster-region>.redshift-serverless.amazonaws.com`
* database
* schema
* user&#x20;
* password&#x20;
* region, e.g. `us-west-2`
* port (if not provided, we assume the default - `5439` )

We recommend sharing these credentials via [sharing mechanisms](https://support.1password.com/share-items/?mac#share-an-item) in password management systems.
