From the previous screenshot, we can see that the only configuration that is unique to Stream Analytics is Streaming units. Streaming units refers to the resources (CPU and memory) assigned for running a Stream Analytics job. The minimum and maximum streaming units are 1 and 120, respectively.
Depending on the amount of data and the queries executed on that data, streaming units must be pre-allocated; otherwise, the job will fail.
It is possible to scale the streaming units up and down from the Azure portal.
