Handle Adversity in Azure Stream Analytics
Imagine you work at your local arcade hall: a cool environment with lots of vintage games and excited customers. Besides operating the machines and talking to customers, you are also the designated IT person. In that capacity, your boss has asked you to make some changes to one of the Stream Analytics jobs the company is running to make it more resilient. You are tasked with implementing an output error policy that retries writing records indefinitely and verifying that the solution actually works.

Enable the Target Storage Container and Observe What Happens
You should undo the change you made before and ensure the storage container is once again writeable by the Stream Analytics job. Once this is the case, you should observe new results flowing in again. You should also observe results that were generated during the downtime being retried and becoming available as well.
