Build an inventory monitoring system with Flink and MongoDB

The tutorial provides a comprehensive guide to building a real-time inventory monitoring system using modern data technologies like MongoDB, Redpanda, and Apache Flink. It likens inventory management to running a corner store, emphasizing the importance of real-time updates to avoid stockouts and manage expiration dates. The system leverages change data capture (CDC) in MongoDB to track inventory changes, with Redpanda facilitating data streaming and Apache Flink processing the data streams. The setup involves configuring a development environment with tools like Docker and Maven, establishing connections between MongoDB and Redpanda using Kafka Connect, and executing an Apache Flink job to process and log data from inventory changes. The tutorial walks through each step, including setting up Docker networks, configuring Kafka topics, and writing Flink applications, providing practical commands and code snippets. This setup allows for automated inventory management, including reordering and managing discounts for near-expiry items, thereby enhancing inventory accuracy and operational efficiency.
