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.process_list_entry.reset();
        if (query_context)
            query_context->setProcessListElement(nullptr);
        if (session)
            session->releaseSessionID();
    }
    void Call::close()
    {
        responder.reset();
        pipeline_executor.reset();
        pipeline.reset();
