Cache Me If You Can: Designing Airline Systems for Billions of Flight Searches
In the airline industry, 99.9% of system traffic is digital waste. For every ticket sold, systems process tens of thousands of searches—a ratio that is exploding as GenAI agents begin shopping on our behalf. In this session, we will discuss the architecture required to survive the so-called "Look-to-Book" crisis. We will look beyond naive caching to explain why simple strategies fail against real-time inventory changes, and discuss how we can build smarter, more complex solutions.

JVM Tail Latency Surgery: where p99/p999 comes from and how to cut it
This talk explains where JVM tail latency really comes from and why p99/p999 can break a system even when p50 looks great. We’ll cover the most common sources of latency spikes: safepoints (not just GC), allocation pressure, OS scheduling and CPU migration, contention, and cache issues like false sharing. You’ll leave with a practical workflow ( one hypothesis → one tool → one proof using JFR, async-profiler, and perf) plus a set of fixes that reliably reduce long-tail latency in production hot paths.

Technical presentation
Soon.
We’ll discuss Java’s built-in concurrency mechanisms (e.g., Thread, Executor, Future) along with popular libraries that facilitate multithreaded workloads (Reactor, Spring WebFlux, Quarkus). You’ll learn why the classic approach to multithreading may no longer suffice and how asynchronous programming shapes modern application design. We’ll also look at where code optimization ends and organizational challenges in distributed architectures begin—such as coordination, data consistency, and resilience against failures.
During the session, we’ll share best practices, design patterns, and lessons learned from years of working with multithreaded and distributed systems. By the end, we’ll answer the question: is concurrency truly a necessity in today’s projects, or rather a powerful tool to be used thoughtfully and with clear purpose?
