Event Grid
Azure's lightweight pub/sub eventing service — for high-volume fan-out of Dataverse change events to many subscribers.
Azure Event Grid is Microsoft's lightweight pub/sub eventing service designed for cloud-scale fan-out. Dataverse can publish change events to Event Grid topics; multiple subscribers can independently subscribe with their own filters. Each subscriber receives the events it filtered for, processed independently — if one subscriber is down, the others are unaffected. Subscribers include Azure Functions, Logic Apps, webhook endpoints, Service Bus queues (for chained durable processing), Event Hubs, and Storage queues. Event Grid scales to millions of events per second and is generally cheaper than Service Bus at high volume, but offers shorter retention (24h default) and less durable processing guarantees. The right pattern when many subscribers need to be notified of Dataverse changes; for transactional integration, prefer Service Bus.
