Unlocking the Power of AWS Lambda and SQS Integration

🔑AWS Lambda is a function as a service offering that provides a managed compute service for serverless architecture.

📩SQS is a managed queuing system that allows you to offload background workloads and parallelize compute.

📈Event Source Mapping in Lambda enables seamless integration with SQS, allowing for efficient and scalable processing of messages from the queue.

🚦Synchronous invocations from Event Source Mapping can lead to throttling when the concurrency level exceeds API limits.

⏰The new maximum concurrency feature in SQS mitigates throttling issues by setting a maximum limit on invocations, preventing overload on external services.

What is AWS Lambda?

—AWS Lambda is a function as a service offering that allows you to write code and run it in response to events, such as changes to data in an S3 bucket or an HTTP request.

What is SQS?

—SQS (Simple Queue Service) is a managed message queuing service that enables reliable and scalable communication between distributed software systems.

How does Event Source Mapping work?

—Event Source Mapping in Lambda is a feature that allows Lambda to automatically poll and process messages from an SQS queue, triggering the Lambda function for each message.

What is throttling in Lambda?

—Throttling occurs when the number of concurrent Lambda function invocations exceeds the concurrency limit, causing some invocations to be throttled and retried.

How does the maximum concurrency feature in SQS help?

—The maximum concurrency feature in SQS allows you to set a maximum limit on the number of invocations from Event Source Mapping, preventing overload on external services and reducing throttling issues.

00:00AWS Lambda and SQS integration is a common serverless pattern that combines the power of Lambda's function as a service and SQS's managed queuing system.

03:36Lambda provides a simple abstraction for developers to write code and execute it in response to events, while SQS allows you to offload background workloads and parallelize compute.

06:45Event Source Mapping in Lambda enables seamless integration with SQS, allowing for the efficient and scalable processing of messages from the queue.

09:55Throttling can occur when the number of concurrent invocations exceeds API limits, leading to messages being retried or discarded.
