Our review
Pros
  • SQL windows, event-time handling, stateful aggregates, and temporal joins
  • Native adapters for Event Hubs, IoT Hub, Storage, Kafka, and Azure SQL
  • Runs in Azure or on Azure IoT Edge devices
  • Unifies batch and streaming pipelines with event-time windowing
  • Supports Java, Python, Go, SQL, and cross-language pipelines
  • Runs through Flink, Spark, Dataflow, or the local Direct Runner
Cons
  • No product-level free plan
  • Dedicated tiers require at least 12 or 36 streaming units
  • Best fit depends on Azure services and ecosystem alignment
  • Execution depends on selecting and operating a compatible runner
  • CDC capabilities vary by connector and runner
  • Requires developer-led pipeline construction rather than hosted ETL workflows
