What must a data architect enable to ensure all streaming data appears in the ingested by profile graph?

To ensure that all streaming data is ingested into the profile graph, it is essential to explicitly enable the data for the profile. This process involves configuring how data is associated with user profiles, allowing the platform to recognize and integrate this streaming data seamlessly into the user profile graph. By explicitly enabling data for profile ingestion, it ensures that the data architect accurately specifies which data streams should contribute to user profiles, making it foundational for building a complete customer view.

Other options, while they may seem relevant, do not directly address the requirement of ensuring that the streaming data is included in the profile graph. User notifications are generally focused on user engagement rather than data integration. Adjusting data processing profiles pertains to how data is processed, not specifically about enabling data for profile integration. Activating streaming events tracking would focus on monitoring data flow rather than necessarily ensuring it is incorporated into user profiles. Thus, specifying data for the profile is the correct and necessary action to achieve the desired outcome.
