A Deep Dive Into OpenSearch Plugin Architecture and Introducing Hot Reload Functionality - Pranav Garg & Aman Kumar, Amazon Web Services In this talk, we’ll take a deep dive into the service architecture behind OpenSearch plugins and how they integrate with the core services. We’ll then transition to explore an exciting enhancement: introducing hot reload functionality for OpenSearch plugins. Traditionally, plugin updates have required full node restarts, impacting uptime and development velocity. This session will demonstrate a prototype for enabling hot reloads, walk through key challenges such as classloading isolation and state management, and highlight what this could mean for the future of OpenSearch extensibility.
