dapr-integration

Dapr pub/sub integration deploys a sidecar that handles asynchronous messaging between services. Define subscription handlers in FastAPI, configure CloudEvent formats, and Dapr routes events to your endpoints—eliminating direct message broker dependencies and simplifying event-driven architecture.

CloudEvent unwrapping extracts the actual event payload from the CloudEvent envelope that Dapr sends to subscription handlers. Parse the metadata and body separately in your handler to access event source, type, and data—ensuring correct event routing and processing in your FastAPI endpoints.

Yes. Dapr Jobs API provides scheduled job execution in Kubernetes with callback processing. Define job schedules and handlers to trigger periodic tasks—complementing pub/sub for workflows that require both event-driven and time-based execution patterns.

Yes. Dapr sidecar injection is a prerequisite; it must be enabled on your Kubernetes namespace or pod. The sidecar intercepts service-to-service calls and manages pub/sub subscriptions and job callbacks, so proper Dapr deployment configuration is essential before integration.

CloudEvent handling requires strict schema compliance; malformed events are dropped. Subscription discovery depends on correct Dapr component configuration; missing or misconfigured pub/sub components cause silent failures. Monitor sidecar logs and validate event routing before scaling.
