Hi Nikhil Thanks for your message, very interesting.
I think it would be great to involve the Polaris project here as well, as a REST Catalog implementation. The Polaris community is discussing storage/backend right now, so it would be the perfect timing to consider leveraging S3 conditional writes (as a plugin for instance first). I would be happy to connect and know more about your perspective about that. Thanks, Regards JB PS: I will be at AWS re:Invent next week, so maybe we can connect there.
