Hi all, We've been using Flight quite successfully so far, but we have identified a new use case on the horizon: being able to both send and retrieve Arrow data within a single RPC call. To that end, I've written up a proposal for a new RPC method: https://docs.google.com/document/d/1Hh-3Z0hK5PxyEYFxwVxp77jens3yAgC_cpp0TGW-dcw/edit?usp=sharing
Please let me know if you can't view or comment on the document. I'd appreciate any feedback; I think this is a relatively straightforward addition - it is essentially "DoPutThenGet". This is a format change and would require a vote. I've decided to table the other format change I had proposed (on DoPut), as it doesn't functionally change Flight, just the interpretation of the semantics. Thanks, David
