How to get messages receive count in Amazon SQS using boto library in Python?

Question

I am using boto library in Python to get Amazon SQS messages. In exceptional cases I don\'t delete messages from queue in order to give a couple of more changes to recover tempo

Answer 1

aws has in-built support for this, just follow the below steps:

1. create a dead letter queue
2. enable Redrive policy for the source queue by checking "Use Redrive Policy"
3. select the dead letter queue you created in step#1 for "Dead Letter Queue"
4. Set "Maximum Receives" as "3" or any value between 1 and 1000

How it works is, whenever a message is received by the worker, the receive count increments. Once it reaches "Maximum Receives" count, the message is pushed to the dead letter queue. Note, even if you access the message via aws console, the receive count increments.
