Building Rust microservices with Apache Kafka

Apache Kafka is an event streaming platform that facilitates effective communication between software applications, particularly microservices, by using concepts like events, topics, producers, and consumers. The article discusses building a microservice in Rust with Kafka, detailing the setup of Kafka brokers, topics, producers, and consumers. It explains the process of creating Rust-based Kafka producers and consumers, which are essential for microservices to handle data streams in real-time. A practical example is provided, demonstrating the construction of a Rust microservice that manages text operations, such as adding and removing text, by processing JSON-formatted events. The microservice interacts with Kafka topics to read actions from an "actions" topic and publish results to a "texts" topic. The article concludes with a demonstration of the microservice's functionality and emphasizes the scalability and distribution benefits of using multiple microservices in complex applications.
