Enhancing Workflow Reliability with Dapr
summary
Demo shows Dapr providing checkpointing at offset level so a workflow processing ten files with 100,000 rows each resumes after a pod crash without reprocessing completed VM IDs, storing progress in a configurable state store (Cosmos DB or Redis). The implementation runs as a Dapr sidecar communicating over HTTP/gRPC, uses placement and sentry services on Kubernetes, and requires increasing MSI authentication timeout for Cosmos. The live example schedules workflows, injects a failure, and successfully resumes from the saved offsets.
