What are Data Actions in Data Cloud and how do they work?

Data Actions allow Data Cloud to trigger a Salesforce Flow in near real time when a segment membership changes or a Calculated Insight crosses a defined threshold. Use cases:

1. A customer enters a "High Churn Risk" segment — a Data Action triggers a Flow that creates a follow-up task for the account manager in CRM.
2. A customer's total spend Calculated Insight exceeds $10,000 — a Data Action triggers a Flow to upgrade the customer to a VIP tier. Data Action configuration:
3. Create a Data Action linked to a segment or CI.
4. Define the trigger condition (enter segment, exit segment, threshold breach).
5. Map Data Cloud attributes to Flow input variables.
6. The target Flow runs in the connected Salesforce org. This enables near-real-time alerting and automated response to data changes without waiting for batch processing.
