Thanks! I've left some initial comments/suggestions to expand it in terms of the format definitions and not the C++ APIs.
I'll also note something like this was proposed a long time ago - there's not very much discussion about it there but for reference: https://lists.apache.org/thread.html/0e5ba78c48cdd0e357f3a4a6d8affd31767c34376b62c001910823af%40%3Cdev.arrow.apache.org%3E (or see the thread '[Discuss][FlightRPC] Extensions to Flight: "DoBidirectional"' from 2019-2020). It might be good to address why the proposed workaround there (union-of-structs) is insufficient for the use cases here (and in FlightSQL). -David On Mon, Jun 21, 2021, at 08:22, Gosh Arzumanyan wrote: > Ah sorry, comments should work now. > > Cheers, > Gosh > > On Mon., 21 Jun. 2021, 14:18 David Li, <lidav...@apache.org > <mailto:lidavidm%40apache.org>> wrote: > > > Thanks!
