To access your data stored on an Amazon Redshift database, you will need to know the server and database name that you want to connect to, and you must have access credentials. Once you have created a connection to an Amazon Redshift database, you can select data from the available tables and then load that data into your app or document.
This connector appears twice in the Add data connection dialog. Once with just the data source name and once with the data source name followed by (via Direct Access gateway). Qlik Data Gateway - Direct Access eliminates the need to open inbound firewall ports, allowing Qlik Sense SaaS applications to securely access firewalled data. If your enterprise data source is located behind a firewall, it is strongly recommended to connect to it via the Direct Access gateway.
For more information on Qlik Data Gateway - Direct Access, see Data gateways.
In Qlik Sense, you connect to an Amazon Redshift database through the Add data dialog or the Data load editor. In Qlik Cloud Data Servicesyou connect to an Amazon Redshift database when onboarding data.

Account properties
Credentials
Credentials are used to prove that a user is allowed to access the data in a connection.
There are two types of credentials that can be used when making a connection in Qlik Sense SaaS. If you leave the User defined credentials check box deselected, then only one set of credentials will be used for the connection. These credentials belong to the connection and will be used by anyone who can access it. For example, if the connection is in a shared space, every user in the space will be able to use these credentials. This one-to-one mapping is the default setting.
If you select User defined credentials, then every user who wants to access this connection will need to input their own credentials before selecting tables or loading data. These credentials belong to a user, not a connection. User defined credentials can be saved and used in multiple connections of the same connector type.
In the Data load editor, you can click the 
underneath the connection to edit your credentials. In the hub or Data manager, you can edit credentials by right-clicking on the connection and selecting Edit Credentials.
See which authentication type applies on each connector's page.

Query Processing Modes |
Specifies how database is queried. |
| Single Row Mode |
This option specifies whether the driver uses Single Row Mode and returns query results one row at a time. Enable this option if you plan to query large results and do not want to retrieve the entire result into memory. Disabling this option increases performance, but can result in out-of-memory errors. |
