[Solved] You have an SQS queue with a DLQ configured and maxReceiveCount set to 4.... Which approach best achieves this? | AWS

AWS - SNS and SQS

You have an SQS queue with a DLQ configured and maxReceiveCount set to 4. You want to ensure that messages that fail processing due to a temporary downstream service outage are retried multiple times before moving to the DLQ. Which approach best achieves this?

ASet maxReceiveCount to 4 and implement exponential backoff in the message consumer

BSet maxReceiveCount to 1 and rely on DLQ for retries

CRemove the DLQ and increase message visibility timeout

DSet maxReceiveCount to 10 and disable retries in the consumer

Step-by-Step Solution

Solution:

Step 1: Understand retry and DLQ roles
maxReceiveCount controls how many times a message is retried before DLQ. Exponential backoff helps avoid flooding retries.
Step 2: Evaluate options for retry strategy
Set maxReceiveCount to 4 and implement exponential backoff in the message consumer combines proper maxReceiveCount with backoff to handle temporary failures effectively.
Step 3: Reject other options
Removing the DLQ is counterproductive as it's needed for persistent failures. Setting maxReceiveCount to 1 limits retries too much. Setting maxReceiveCount to 10 and disabling retries in the consumer is not effective for temporary outages.
Final Answer:
Set maxReceiveCount to 4 and implement exponential backoff in the message consumer -> Option A
Quick Check:
Retries + backoff before DLQ = best practice [OK]

Quick Trick: Use maxReceiveCount with backoff for retries before DLQ [OK]

Common Mistakes:

Setting maxReceiveCount too low
Removing DLQ mistakenly
Disabling retries in consumer
