You can create connections to databases of this type that are managed by your enterprise or are hosted in cloud infrastructure. The required configuration is the same. The cloud-based version is labeled on Amazon RDS. In the Create Connection dialog, you can search for that term.

If you are connecting AACAAC to any relational source of data, such as Redshift or Oracle, you must add the Alteryx Service to your allowlist for those resources. For more information, go to Allowlist Platform Service.

Configure

To create this connection:

On the Import Data page, select the Plus sign. Then, select the Relational tab. Select the Alloy DB card.
You can also create connections through the Connections Page.

Modify these properties as needed:

Property	Description
Host	Enter your fully qualified hostname. Example: my.postgres.server
Port	Set this value to `5432`.
Connect String Options	Insert any additional connection parameters, if needed.
Enable SSL	Check the box to enable SSL connections to the database. 注記 The database server might require additional configuration. For more information, please consult the distribution documentation.
Database	Enter the name of the database on the server to which to connect.
User Name	Username to use to connect to the database.
Password	Password associated with the above username.
Test Connection	After you've defined the connection credentials type, credentials, and connection string, you can validate those credentials.
Advanced options: Default Column Data Type Inference	Set to `disabled` to prevent the platform from applying its own type inference to each column on import. The default value is `enabled`.
Advanced options: Enable SSH Tunneling	If available, use the SSH tunneling options to configure SSH tunneling authentication between AACAAC and your database. 注記 SSH tunneling is available on a per-connection basis. It might not be available for all connections. For more information, go to Configure SSH Tunnel Connectivity.
Connection Name	Display name of the connection.
Connection Description	Description of the connection that appears in the application.

Connection URL

AACAAC builds the connection URL from the properties you provided:

jdbc:postgresql://<host>:<port>/<database><connect-string-options>

Connect String Options

The connect string options are optional. If you are passing additional properties and values to complete the connection, the connect string options must be structured in the this manner:

?<prop1>=<val1>&<prop2>=<val2>...

Where:

<prop> : The name of the property.
<val> : The value for the property.

Delimiters:

? : Any set of connect string options must begin with a question mark.
& : All additional property names must be prefixed with an ampersand (&).
= : Property names and values must be separated with an equal sign (=).
