Wangyi worked on enhancing the sgl-project/sglang and vllm-project/aibrix repositories by building a pluggable storage backend for the hierarchical KV cache and integrating it into containerized deployments. He implemented the AIBrix KVCache backend, allowing runtime selection of storage backends without code changes, and reinforced the integration with unit tests to ensure reliability. Using Python, Docker, and CI/CD workflows, Wangyi streamlined the build and deployment process by packaging the KVCache wheel into the SGLang Docker image. He also addressed stability issues in the hicache storage layer, refining cache eviction logic and adding assertions to improve system robustness and maintainability.

Month: 2025-09 Overview: - Focused on delivering a new pluggable storage backend for the hierarchical KV cache in sgl-lang, enabling teams to switch storage backends without code changes. All work centered on sgl-project/sglang with a clear path for future backends. Key outcomes: - Delivered AIBrix KVCache storage backend integration, including new storage class and configuration to support AibrixKVCacheStorage. The backend can be selected via the --hicache-storage-backend argument, enabling runtime flexibility for deployment environments. - Strengthened test coverage with unit tests validating the integration and its behavior, reducing risk of regression when modifying storage backends. - Codebase improvements to support pluggable storage backends, laying groundwork for additional backends and easier future maintenance.
