relay

Relay orchestrates Kafka-based event streaming by connecting producers and consumers to topics like orders.order.* and product.* for real-time data flow. Define your topic routing, and Relay handles transformation, replay, and dead-letter queue management automatically across the distributed platform.

Relay delivers events as webhooks, email, and in-app notifications with user preference support. Route Kafka events through Relay's notification pipeline to trigger webhook calls and email delivery based on event type and user settings.

Relay generates and synchronizes feeds by consuming events from Kafka topics and distributing normalized data to downstream services. Use feed management to keep product catalogs, order states, and inventory levels consistent across the platform.

Relay handles failures through dead-letter queues that capture events that fail processing, allowing you to replay them later. Event replay ensures no data loss and lets you recover from transient failures or reprocess events after fixes.

Relay integrates natively with Beam, Prism, Channels, and Merchants for end-to-end event orchestration. These services consume routed events and feed updates from Relay to maintain synchronized state across the platform.

Relay supports event replay to reprocess historical data and dynamic topic routing for rerouting events post-deployment. Replay lets you recover from bugs; routing flexibility avoids service restarts when event paths change.
