Randalo media pipeline: from upload to finished media Diagram

Upload

Public.Api creates a purpose-scoped session; the app sends chunks straight to Upload.Api
Upload.Api validates media signatures and checks the SHA-256 server-side
A scheduled cleanup job removes expired, consumed and failed sessions

Orchestration

Media.Service writes the media row and a dispatch journal in one Azure Table partition
Separate MassTransit state machines for images and videos persist their sagas in Azure Tables
A strictly increasing workflow revision keeps redelivered messages idempotent

Workers

Every file is scanned first; only clean media continues
Queue-triggered Container Apps Event Jobs scale to zero when idle
The app follows Requested, VirusScanning, Processing, Completed via SignalR
