AlloyDB Connections

This connection is in early preview. It is read-only and available only in SaaS product editions. For more information on early previews, go to Early Preview Connection Types.

If you are connecting AAC 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.
