Yes, protoc no longer bundles protoc binaries and instead uses the system versions if available, or builds from source if not - see https://github.com/tokio-rs/prost/pull/610 Unfortunately the arrow-flight specification is using the somewhat new [explicit presence](https://github.com/protocolbuffers/protobuf/blob/main/docs/field_presence.md#how-to-enable-explicit-presence-in-proto3) feature of protobuf, and this will cause issues if compiling with an older version of protoc which doesn't support it. Perhaps we could check the version of the protoc binary and return a more helpful error message if it is too old 🤔 -- This is an automated message from the Apache Git Service.
