The Stream Firehose with SQS, Lambda, and Redis

Stream has introduced a feature called Firehose to enhance its real-time platform, allowing users to monitor feed changes via Amazon SQS or webhooks, complementing the existing websocket framework. This addition is specifically designed to improve application speed for real-time functionalities such as games and chat applications, with the infrastructure capable of supporting sub-500 millisecond round-trip times. The blog post provides a step-by-step guide on integrating Firehose into Stream applications using AWS Lambda, Simple Queue Service (SQS), and Redis, detailing the process of setting up an IAM role, creating a Stream application, configuring a new SQS queue, and setting up a Lambda function to handle message processing. It also covers the creation of a serverless infrastructure to generate emails and push notifications, highlighting the use of Redis as a datastore for queuing messages and enabling batch notifications. The post concludes by encouraging readers to share their experiences and any queries regarding the setup process.
