Upcoming  Events

Join us for an evening filled with learning, networking, and festive fun as we explore how Hazelcast Platform extends far beyond caching to support complex, real-world enterprise needs. See Hazelcast Platform in action Get exclusive insights from our guest speaker, Humphrey Fu, Engineering Lead at Santander, as he shares the journey of adopting and evolving Hazelcast Platform within Santander’s FX platform. What started as a simple caching solution for a single data type is now a core component of Santander’s infrastructure supporting messaging, compute grids, and static data distribution. Humphrey will discuss the project’s key challenges, milestones, and decisions involved in scaling Hazelcast Platform within a complex financial environment - all from a practitioner’s perspective.

Designing APIs is an art, a creative exercise. Getting it right for right now is hard, getting it right for tomorrow is even harder. This talk explored designing resilient Java APIs for upward compatibility, consumability, and flexibility. We discussed the practicalities of ideas like encapsulation and inheritance, looked at wider elements like consistency, and effective communication of intent, and covered concepts like the Open-Closed Principle, Semantic Versioning, and other elements that are essential for seamless API evolution. We also reviewed real-world examples, Java gotchas, the latest Java API capabilities, API Check tools, and data and looked at what Maven Central tells us about the challenge we all face (and just how good we collectively are). Amazingly, good API design not only helps with evolving for the future, it makes the API more secure and reduces maintenance overheads - all while remaining flexible and consumable. Time to break those bad design habits before they begin.
