Event-Driven Pipelines With Apache Pulsar and Go

A Practical Walkthrough Most distributed systems eventually hit a wall with their messaging layer, whether it’s Kafka’s tight coupling between compute and storage, RabbitMQ’s limited replay capabilities, or the operational overhead of managing multiple tools for queuing and streaming. Apache Pulsar was engineered to address these gaps from the ground up. In this article, we’ll dissect a working Go-based demo that wires together a Pulsar producer, consumer, and Prometheus monitoring layer into a cohesive, observable messaging pipeline.
