Yongke Zyk developed cache-aware interfaces for the MasterService component in the Mooncake repository, focusing on enhancing the scheduler’s ability to make data-driven resource allocation decisions. By designing new APIs in Go and C++ that expose cache metadata such as all keys, segments, and segment capacity and usage, Yongke enabled the scheduler to query precise cache information and optimize request routing. This work addressed the challenge of reducing scheduling guesswork in distributed systems and laid the foundation for future improvements in cache observability. The implementation demonstrated depth in API design, caching strategies, and system programming within a distributed environment.
