Your company deploys thousands of sensors.
You plan to join the data from the sensors by using Azure Data Factory. The reference data file refreshes every 30 minutes.
You need to include the path to the reference data in Data Factory.
Which path should you include?
A. products/{date}/{time}/product_list.json
B. products/{sensor_name}/product_list.json
C. products/{batch}/product_list.json
D. products/{time}/product_list.json
Correct Answer: A
Explanation/Reference:
Stream Analytics supports taking reference data stored in Azure blob storage as one of the "inputs" for the job. To enable support for refreshing reference data the user needs to specify a list of blobs in the input configuration using the {date} and {time} tokens inside the path pattern. The job will load the corresponding blob based on the date and time encoded in the blob names using UTC time zone.
For example if the job has a reference input configured in the portal with the path pattern such as: /referencedata/{date}/{time}/customertable.csv where the date format is "YYYY/MM/DD" and the time format is "HH/mm" then the job will pick up a file named /referencedata/2015/07/26/08/30/customertable.csv at 8:30 AM on July 26th 2015 UTC time zone.
