You use Azure Stream Analytics to receive data from Azure Event Hubs and to output the data to an Azure Blob Storage account.
You need to output the count of records received from the last five minutes every minute.
Which windowing function should you use?

A. Session

B. Tumbling

C. Sliding

D. Hopping








 

Suggested Answer: D

Hopping window functions hop forward in time by a fixed period. It may be easy to think of them as Tumbling windows that can overlap and be emitted more often than the window size. Events can belong to more than one Hopping window result set. To make a Hopping window the same as a Tumbling window, specify the hop size to be the same as the window size.
