| ### SQS Polling and Charges | |||
| AWS Lambda maintains a continuous "poller" for SQS messages, which invokes the Lambda function upon receiving messages. This process, while eliminating the need for manual polling, generates continuous SQS requests, incurring charges, [though the first 1M requests of each month are free as part of the AWS free tier](https://aws.amazon.com/sqs/pricing/#:~:text=First%201%20Million%20Requests/Month). | |||

I think it might be best to be precise here. I'd rather not create fear for users.
I had in mind that if you deploy 1 queue it fits in the free tier, can you confirm? I'd rather make that obvious in the docs if we mention costs.

| To mitigate these charges, consider adjusting the `MaximumBatchingWindowInSeconds` in your Lambda configuration. This setting delays message delivery to the Lambda function when batching, aiming to assemble the largest possible batch within the specified timeframe, counted as a single SQS API request. |

Updating documentation based on our discussion on #1760 in an attempt to be helpful!
I wonder if this information would be better in a more centralised area of the docs that can provide more detailed information about different parts of the infrastructure layer work. I couldn't see anything like this so for now I've added the information to the Symfony Messenger and Laravel Queue sections.
