> See [this GitHub issue|https://github.com/apache/arrow/issues/11657]: when building a combined gRPC/Flight service, care must be taken not to link gRPC twice on accident. This is noted briefly in the [docstring|https://github.com/apache/arrow/blob/3e554c3703557b422fd762fe9c3844e514b32149/cpp/src/arrow/flight/server.h#L152-L159] but we should be more detailed and perhaps add prose documentation. We should also note this in the [example|https://github.com/apache/arrow/blob/3e554c3703557b422fd762fe9c3844e514b32149/cpp/examples/arrow/flight_grpc_example.cc].
