Xiangnebula contributed to the apache/amoro repository by architecting and delivering modular backend features focused on maintainability and scalability. Over six months, they refactored core Java services to decouple tightly bound components, introduced stateless management layers, and generalized runtime interfaces to support flexible, pluggable backends. Their work included implementing a persistent, database-backed HTTP session store using SQL and enhancing system reliability through configuration management and code abstraction. By modularizing table process management and introducing factory-based runtime instantiation, Xiangnebula enabled extensible runtime strategies and streamlined future enhancements. The depth of these changes improved code organization, testability, and long-term maintainability across the codebase.

Sep 1, 2025September 2025 monthly summary for apache/amoro: Implemented a new modular runtime architecture by introducing the TableRuntimeFactory interface and its default implementation to manage table runtimes. This change refactors the table service to instantiate runtimes via the factory, enabling plug-in, modular, and extensible runtime implementations and paving the way for future runtime extensions.

Aug 1, 2025Monthly performance summary for 2025-08 focusing on architecting improvements in apache/amoro. Delivered a major architectural refactor to generalize TableRuntime and table process management, introducing a generalized TableRuntime interface, separation of runtime state from metadata, and modularized table process storage. This foundational work enables flexible runtime backends and easier maintenance across optimizers, maintainers, schedulers, and related components. No major bugs fixed this period; the work centers on design and groundwork that unlocks future improvements. Demonstrated strong system design, cross-component collaboration, and codebase modernization.

Feb 1, 2025February 2025: Delivered architecture refactors and reliability improvements for the apache/amoro project, focusing on modularity, startup resiliency, and enhanced SQL capabilities. Key features include decoupling Amoro service controllers from TableService and introducing cancelProcess in OptimizingService, plus integrating a new MyBatis language driver for richer SQL support. The AMS dashboard was refactored to a stateless OverviewManager, removing OverviewCache, with configuration updates for cache refresh intervals and size, and a startup reliability fix that aligns overview-cache.refresh-interval formatting (3min). These changes improve maintainability, reduce startup risks, and enable faster deployments. Overall impact: improved scalability, testability, and business value through more reliable, performant services, clearer ownership, and better deployment velocity.
