Thanks, Mehul! Having a dedicated section for Fluss × Iceberg makes perfect sense, and the roadmap looks great to me. I’m really excited to see this come to life this year! I’ve already added it as a link in the umbrella roadmap.
For the next step, we should decide how to update the Roadmap page on the website (https://fluss.apache.org/roadmap). One simple approach is to replace it with a direct link to this GitHub discussion, so it stays up to date and benefits from community input. What are your thoughts? Do you have other ideas on how we should present it?
