Handling Partial Batch Failure When Processing SQS Messages with a Lambda Function
Amazon Simple Queue Service (SQS) is a fully managed message queuing service that enables you to decouple and scale microservices, distributed systems, and serverless applications. One common use case for SQS is to process messages from a queue as a batch using a Lambda function. However, in some cases, you may encounter partial batch failure, where some messages in the batch are processed successfully, while others fail. In this case, you need to handle the partial batch failure to ensure that the messages that failed to process are retried, while the messages that succeeded are not processed again.
Amazon SNS payload-based message filtering
By default, an Amazon SNS topic subscriber receives every message that's published to the topic. To receive only a subset of the messages, a subscriber must assign a filter policy to the topic subscription.
Amazon SQS local development using LocalStack
Amazon SQS is a reliable, highly-scalable hosted queue for storing messages as they travel between applications or microservices. Amazon SQS moves data between distributed application components and helps you decouple these components. That means to test your application you will need to connect to the Amazon SQS service each time. For development and testing purposes, you’ll likely want to test locally.
