Introduction Response streaming is a new invocation method that enables your functions to progressively stream response payloads back to the clients. Instead of waiting for the entire data to be ready, your applications can now receive chunks of data as soon as they become available. This means faster loading times and a more responsive user experience. Response Streaming vs. Non-Streaming (Buffering) To quickly get an idea of how it works, we need to see it in action. Below, we show two functions that have the simple task of displaying a message in HTML. The non-streaming function introduces a delay of [...]

Introduction In the first part of this post, we covered the concept behind event filtering in AWS Lambda and learned how it could help you save money by invoking functions only when necessary. Now it's time to put that knowledge into practice. In this part 2, we’ll see event filtering in action using Amazon Simple Queue Service (SQS) as the event source. Overview A user sends a JSON message to the SQS queue. Event source mapping picks up the message from the queue and evaluates it against the specified filtering criteria. Event source mapping invokes the Lambda function synchronously when [...]

Problem statement You are primarily billed based on how long your Lambda functions run and how often it is invoked. This is why AWS Lambda is great for scheduled jobs, short-duration tasks, and event-based processes. But does this mean you shouldn’t use them for high-volume traffic applications? Well, the short answer is... it depends. Whether or not to use AWS Lambda for high-volume traffic workloads ultimately depends on the requirements of your application and the cost trade-off you're willing to make. Regardless, if you ever find yourself wanting to use Lambda in a high-activity application like stream processing, it’s good [...]
