Moving a large-scale metrics pipeline from StatsD to OpenTelemetry / Prometheus

A large-scale metrics pipeline was migrated from StatsD to OpenTelemetry and Prometheus, showcasing the scalability of the new system. This move is significant as it highlights the growing adoption of OpenTelemetry and Prometheus in the industry. Engineers can learn from this example and consider migrating their own pipelines to take advantage of the benefits of OpenTelemetry and Prometheus. The migration process involved significant changes to the system architecture and required careful planning and execution. The outcome demonstrates the feasibility of using OpenTelemetry and Prometheus for large-scale metrics collection.
