如何高效地分离Thrift客户端的连接、协议和调用？

func fundinfoserviceclient(ip, port string) (*fundinfo.fundinfoserviceclient, thrift.ttransport, error) {
    transportFactory := thrift.NewTFramedTransportFactory(thrift.NewTTransportFactory())
    protocolFactory := thrift.NewTBinaryProtocolFactoryDefault()

    transport, err := thrift.NewTSocket(net.JoinHostPort(ip, port))
    if err != nil {
        return nil, nil, fmt.Errorf("无法解析地址: %w", err)
    }

    tTransport := transportFactory.GetTransport(transport)
    client := fundinfo.NewFundInfoServiceClientFactory(tTransport, protocolFactory)

    if err := tTransport.Open(); err != nil {
        return nil, nil, fmt.Errorf("无法连接到 %s:%s: %w", ip, port, err)
    }

    return client, tTransport, nil
}

func processFundInfo(ctx context.Context, fundcode string, ip, port string) (*fundinfo.FundInfo, error) {
    client, tTransport, err := fundinfoserviceclient(ip, port)
    if err != nil {
        return nil, err
    }
    defer tTransport.Close()

    res, err := client.GetFundInfo(ctx, fundcode)
    if err != nil {
        return nil, fmt.Errorf("调用GetFundInfo失败: %w", err)
    }
    return res, nil
}
