AEP/RTCDP does not natively support automatically deleting profile records based on their age (e.g., removing records older than 30 days). The platform is designed to maintain comprehensive customer profiles and enable a full 360-degree customer view over time.
While there are mechanisms to delete identities from the profile store, these are primarily intended to fulfill GDPR or other regulatory compliance requirements. These options have specific guardrails and limitations and are not suitable for general data lifecycle management.
If your use case strictly requires removing records older than 30 days, one practical approach would be to periodically ingest only the current valid profiles into a new dataset and then drop the old dataset. This ensures that only the most recent records remain available in both the data lake and profile store.
