Question

The benefit/s of SQS long polling:

A. Reduction of the number of empty responses
B. Eliminates false empty responses
C. Reduces resources required for polling queues
D. All of the above

Answer 1

Long polling with SQS provides benefits such as reducing empty responses, eliminating false empty responses, and reducing resource requirements for polling queues.

Step-by-step explanation:

Long polling is a technique used in web development to reduce the number of empty responses and eliminate false empty responses when polling a server for new data. SQS (Simple Queue Service) is a messaging queue service provided by Amazon Web Services (AWS). When using SQS long polling, the client waits for a specified period of time for new messages from the queue. This reduces the number of empty responses and ensures that the client receives messages as soon as they become available.

In the context of SQS long polling, option D is correct - All of the above. Long polling reduces the number of empty responses, eliminates false empty responses, and reduces the resources required for polling queues. By combining these benefits, more efficient and cost-effective message polling can be achieved.
