Ever wondered what’s actually happening when you hook SQS up to AWS Lambda? In this episode, we go behind the scenes to unpack the part most people never see: the polling. Lambda still needs to poll SQS for messages, but instead of you writing and managing that code, Lambda runs a fleet of pollers on your behalf. Once messages arrive, Lambda delivers them to your function in a batch as an SQS event, so you can iterate through each message and process them one by one.

We Are .NET

When AWS Lambda is configured with an SQS trigger, it doesn't eliminate polling — it abstracts it. Lambda internally manages a fleet of pollers that continuously pull messages from SQS on your behalf. When messages arrive, they are batched and delivered to your Lambda function as an SQS event, which you can then iterate over. The polling logic still exists; Lambda just hides it from the developer.
