Hightouch Event Streaming — Real-Time Destination Forwarding (2026)

Official Hightouch event streaming documentation. Original queue URL (/docs/destinations/azure-event-hubs) returned 404 and no dedicated Azure Event Hubs destination page was found in the current docs; this event-streaming overview covers real-time destination forwarding including streaming-platform targets.

Key facts surfaced (2026-05-20):

• Sends events directly to downstream destinations in real-time without warehouse round-trip; sub-second to seconds latency.
• Enables latency-sensitive workflows: triggering messages, updating consent, real-time personalization.
• Any catalog destination supporting event forwarding is eligible (specific destination support listed per-destination).
• Event processing pipeline: event received → contracts validate schema → Event Function transforms payload → filters applied → field mappings applied → delivered to destination with automatic retries.
• Note: Azure Event Hubs is not listed as a named event streaming destination in current docs; Module 13 Azure streaming activation may route through Event Streaming to Azure Blob Storage or Azure Functions instead.
• Curriculum reference: real-time activation path for configure-cloud-streaming-activation-destination (Module 13).
