PROFILE

Yi Wang

Worked on enhancing the sgl-project/sglang and vllm-project/aibrix repositories by developing a pluggable storage backend for the hierarchical KV cache and integrating AIBrix KVCache into the SGLang Docker image. Focused on backend development and cache management, the approach included implementing a new storage class in Python, enabling runtime backend selection, and strengthening test coverage to ensure reliability. Addressed stability in the hicache storage layer by refining eviction logic and adding assertions to prevent runtime errors. Leveraged Docker and CI/CD workflows to deliver a reproducible, containerized integration, streamlining deployment and laying the foundation for future performance improvements 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.
