Hello Everyone, Thanks, Yufei, for organizing this, and Huaxin, for all the great work on the implementation!
I'm also very interested in this area and would love to get involved and help with reviews! I'll start going through the PRs shared above to better understand the overall UDF design and implementation. I'm based on the West Coast (PT), and my schedule is generally flexible except on Wednesdays. I'd be happy to join the sync! Thanks again, and I look forward to learning more and contributing!
