A streaming workload means data is generated continuously and ingested in near real time. Telemetry from edge/IoT devices is a classic example of streaming workloads because the devices constantly push data (sensor readings, logs, metrics). A). sending transactions daily # batch workload (not streaming). B). sending metadata every 30 minutes # periodic batch, not continuous streaming. C). sending old transactions to archive # cold data archival, not streaming. Reference: Azure Stream Analytics overview
