Does Lambda with RabbitMQ-trigger batch messages from multiple queues

Question

Hi,

I have a Lambda with a single `lambda_handler` function and multiple YAML files with different env vars.
This Lambda should be triggered by RabbitMQ, each YAML file contains one RabbitMQ queue.
As I understand from the documentation, Lambda batches messages and processes them at once, but what I didn't understand is whether an event contains messages from multiple queues.
If it does,  how can I distinguish between them and apply the different configuration according to each queue's YAML file's?

I haven't used it myself, but As I understand you need to specific a queue every time you configure a lambda function as destination, That suggest that while there will be a batch of message but they all will be from same queue.

And since the sourceArn content queue name you can use that to decide which configure to pick.
