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).
{
        io.onException();
        LOG_ERROR(log, fmt::runtime(getExceptionMessage(exception, true)));
        if (responder && !responder_finished)
        {
            try
            {
                
                addLogsToResult();
            }
            catch (...)
            {
                LOG_WARNING(log, "Couldn't send logs to client");
            }
            releaseQueryIDAndSessionID();
            try
            {
                sendException(exception);
            }
            catch (...)
            {
                LOG_WARNING(log, "Couldn't send exception information to the client");
            }
        }
        close();
    }
    void Call::onFatalError()
