This article discusses the problem of slow-draining queues in microservice-based applications, particularly those using AWS Lambda functions and containers with AWS Simple Queue Service (SQS) message queueing. Repeated failures in processing SQS messages can lead to increased costs, reduced reliability, and hindered performance downstream components. Lumigo is introduced as a cloud-native observability platform that helps debug and solve this issue by providing distributed tracing capabilities, code error analysis, monitoring key metrics, log analysis, and more. A coded example using Node.js Lambda function demonstrates how to implement Lumigo tracing capabilities into the application, allowing developers to gain insight into message processing behavior and quickly pinpoint issues when they arise.
