**Is your feature request related to a problem or challenge? Please describe what you are trying to do.** I'm trying to use the arrow format for an DataFusion group operator. For that it would be super helpful do detach/own a row (acting as a group key). **Describe the solution you'd like** Introduce a new type `OwnedRow` that does not borrow buffer (for that particular row, not the entire buffer) and type but owns it. **Describe alternatives you've considered** Make `Row` a copy-on-write type (similar to `Cow`). However this would introduce an enum-dispatch overhead to every row access and I think it's easier to do this on a type level (since I guess all users know if they own the row or not). **Additional context** \- -- This is an automated message from the Apache Git Service.
