Simulation Details

PulseSync is a leading technology company specializing in real-time monitoring systems for high-concurrency applications. Its flagship product, the PulseSync Live Dashboard, processes over 1 million data points per second, providing continuous updates on critical metrics like CPU usage, memory consumption, and disk I/O. This tool enables clients to identify and resolve performance bottlenecks in under 30 seconds, a significant improvement over the industry average. Built on Java Spring Boot with REST APIs and PostgreSQL, PulseSync’s technical stack has delivered reliable solutions for years. However, growing client demands for real-time insights have exposed the limitations of REST APIs in handling continuous data streams. To address this, PulseSync is exploring Spring WebFlux, a framework that introduces reactive programming principles, promising scalability for up to 10,000 concurrent connections per server. Despite its potential, WebFlux adoption has faced skepticism due to its steep learning curve, debugging complexities, and concerns about long-term maintainability. PulseSync fosters a collaborative environment, hosting workshops and hackathons to explore emerging technologies, including reactive programming, to balance innovation with practicality.

You will step into the role of a Java Developer tasked with enhancing the DashboardService class to demonstrate the advantages of Spring WebFlux for PulseSync’s real-time monitoring dashboard. Your mission is twofold: first, implement three methods—updateMetricValue, getMetricsAboveThreshold, and simulateMetricUpdate—to simulate real-time data updates and showcase the benefits of reactive programming. Second, engage in one-on-one chats with Morgan Kwon, the Lead Technical Manager, to refine your code, address her skepticism, and justify your technical decisions. Morgan is concerned about the complexity and maintainability of WebFlux, so you must articulate its advantages clearly and practically. Success requires delivering a functional demo that meets performance benchmarks while fostering collaboration and innovation within the team.

– Implement the three required methods in the DashboardService class using Spring WebFlux principles to simulate real-time data updates.
– Engage in real-time chats with Morgan Kwon to address her concerns, justify your technical choices, and refine the code based on her feedback.
– Demonstrate the practical benefits of WebFlux, including improved scalability, reduced thread-blocking, and efficient resource utilization.
– Ensure the updated DashboardService class meets performance benchmarks, including sub-second response times and scalability for at least 5,000 concurrent users.
