Hi @vitlibar,
In http implementation, ClickHouse will return format of query result in header `X-ClickHouse-Format`. Can we return format in gRPC response as well? This helps client like JDBC driver for deserialization(without the need for parsing the query).
reading_query_info.set(false);
            });
        };
        auto finish_reading = [&]
        {
            if (reading_query_info.get())
            {
                Stopwatch client_writing_watch;
                reading_query_info.wait(false);
                waited_for_client_writing += client_writing_watch.elapsedNanoseconds();
            }
            throwIfFailedToReadQueryInfo();
            query_info = std::move(next_query_info_while_reading);
            initial_query_info_read = true;
        };
        if (!initial_query_info_read)
        {
            
            start_reading();
        }
        
        finish_reading();
        if (isInputStreaming(call_type))
        {
            
            
            start_reading();
        }
    }
