Helidon Nima: Loom-Based Microservices Framework - GeeCON Prague 2022

Explore the groundbreaking Helidon Nima microservices framework in this GeeCON Prague 2022 conference talk. Delve into how Project Loom in JDK revolutionizes the performance vs. simplicity paradigm, enabling high concurrency without sacrificing code simplicity. Discover the benefits of Helidon Nima's Loom-based server design, featuring fully synchronous routing that allows blocking while maintaining high performance under heavy loads. Learn about the challenges, advantages, and impact on application development in this new environment. Examine the potential end of reactive programming as the talk covers topics such as expensive concurrency, virtual threads, Project Loom, reactive vs. imperative programming, Nima server features, thread models, and performance comparisons. Gain insights into Helidon 4.0.0-ALPHA2, Helidon MP 4, and strategies for offloading obstructive workloads in Nima development.
