Question

The engineering team at an e-commerce company wants to migrate from SQS Standard queues to FIFO queues with batching. As a solutions architect, which of the following steps would you have in the migration checklist? (Select three)

a) Change the message deduplication ID strategy
b) Update the application code to work with the FIFO message format
c) Modify the application to process messages in batches
d) Enable long polling for improved efficiency

Answer 1

To migrate from SQS Standard queues to FIFO queues with batching, the migration checklist should include: changing the message deduplication ID strategy, updating the application code to work with the FIFO message format, and modifying the application to process messages in batches.

Step-by-step explanation:

When migrating from SQS Standard queues to FIFO queues with batching, there are three important steps to include in the migration checklist:

1. Change the message deduplication ID strategy: FIFO queues require a different message deduplication technique compared to standard queues. This change ensures that duplicate messages are not processed.
2. Update the application code to work with the FIFO message format: Since FIFO queues have a strict ordering requirement, the application code needs to be modified to handle the message format, ensuring correct ordering and deduplication.
3. Modify the application to process messages in batches: Batching helps in improving throughput and efficiency. By modifying the application to process messages in batches, the engineering team can make the most out of the FIFO queues with increased scalability.
