AEP Mapped Attributes Per Destination — 50 (Performance Guardrail)

constraint.aep-mapped-attributes-per-destination-50 ↗

Adobe Experience Platform performance guardrail recommending a maximum of 50 mapped profile attributes per destination instance. Not system-enforced — AEP does not hard-block at 50 mapped attributes — but performance degradation is expected above this threshold. Applies during the field-mapping step in the Destinations workflow: each profile attribute (first name, email, loyalty tier, propensity score, product affinity, etc.) mapped to a destination field counts against this limit. Highly enriched destination payloads (personalization platforms requiring 40–60 profile attributes for content rendering) approach this guardrail and require attribute prioritization.
