> > @agneborn98 It looks like it's an issue with the Rust server. I'm going to guess that they made a similar mistake to one I made with my original implementation of the Go Flight server/client. > > The original .proto file appeared to claim that the return from SchemaResult should just be the FlatBuffers Schema message on it's own. But the convention that was established by the C++ and Java implementations was that it should be a full IPC encoded schema message, so my original implementations didn't interact well with those until I fixed it to be a full IPC encoded message. It's possible the Rust server implementation makes the same mistake? Not sure. > > why c++ java return the full IPC encoded schema message for the method `GetSchema` defined in the `.proto` or not the FlatBuffer for the schema message? > > > But given that you're getting a similar issue from two different flight client implementations, i'm inclined to think the issue is with the Rust server.... but I'm not familiar enough with rust to debug that. > > Hi @zeroshade , I from arrow-rs community and try to resolve [apache/arrow-rs#2445](https://github.com/apache/arrow-rs/issues/2445) about the `get_schema`. > > I think the gab between arrow-rs and c++/go is the different implementation for the `GetSchema`. As description from @zeroshade , the c++/go will convert the schema to the full flight message, but the rust don't do like that, the rust just return the bytes from the flatbuffer. -- This is an automated message from the Apache Git Service.
