Worked on stabilizing and integrating the DataFusion execution path with Delta Lake Rust in the langchain-ai/delta-rs repository by unifying the SessionState across both systems. Refactored the OptimizeBuilder to accept SessionState, which improved memory management and enabled better concurrency when running on Kubernetes. Standardized SessionState usage throughout DataFusion APIs, reducing cross-component coupling and simplifying execution context management. These changes enhanced system stability and scalability under load, laying the foundation for future performance improvements in production environments. The work involved deep API refactoring and code unification, leveraging expertise in Rust, Python, distributed systems, and software design to address integration challenges.
