GRPC消息结构

我正在将旧版应用程序（微服务和整体软件的一部分）迁移到使用GRPC的过程中。整个代码库当前位于GO中。

我已经开始对消息建模，它们看起来与我在应用程序代码中使用的结构非常相似。我两次定义相同的对象似乎很奇怪，但是将消息对象用作核心结构也很奇怪。似乎我将有大量内存密集型数据封送处理。以下是消息和结构的示例，以及它们之间的相似程度。

在决定如何对邮件进行建模方面，是否有任何建议/最佳做法？它们是否应该与我的核心结构保持一致？我是否应该不在乎从Golang结构到消息的所有编组？

如果我问的是一个基本问题，请原谅我，因为我对协议缓冲区和GRPC非常陌生。

消息原型定义：

message Profile {
    string UID = 1;
    string ContactEmail = 2;
    google.protobuf.Timestamp DateOfBirth = 3;
    float WeightInKilos = 4;
    string Gender = 5;
    string Unit = 6;
    string CurrentStatus = 7;
    string Country = 8;
    string ExperienceType = 9;
    google.protobuf.Timestamp DateJoined = 10;
    repeated Ability Abilities = 11;
    repeated Role Roles = 12;
    repeated TermsAndConditionsAcceptance TermsAndConditionsAcceptances = 13;
    string TimeZone = 14;
    repeated BaselineTestResults BaselineTests =15;
    //Excluded UpdatedDate as other domains shouldn't need it
    string FirstName =16;
    string LastName =17;
    string DisplayName = 18;
    string State = 19;
    repeated google.protobuf.Any Preferences = 20;
    Thresholds Thresholds = 21;
    string StripeCustomerID = 22;
}

结构Def：
