A detailed case study on the evolution of a Server-Sent Events (SSE) dual-queue architecture is presented, documenting eight major iterations that transformed the system from facing Out-of-Memory (OOM) errors to handling network drift gracefully. The author shares the technical challenges encountered at each stage, including queue management, memory optimization, and network stability. This narrative provides practical lessons for backend engineers and system architects building real-time data streaming systems. The content is evergreen, offering insights that remain relevant as event-driven architectures evolve. It is a valuable resource for teams looking to improve the resilience and performance of their SSE implementations.
This post chronicles the evolution of a Server-Sent Events (SSE) dual-queue architecture through eight iterations, addressing issues from Out-of-Memory (OOM) errors to network drift.
