Protobuf as data model class in Java

[Zhu Li]

Hello there,

Is it encouraged to use protobuf generated classes as data model classes directly?

A reddit post https://www.reddit.com/r/golang/comments/rdkqwv/comment/ho1sfp9/?utm_source=share&utm_medium=web2x&context=3says suggests "having a translation layer between persistence, transmission, and business logic if you are building for the long term". And there might be more related discussion online. What's your suggestion? Do readers who use protobuf classes as data model classes directly regret the decision? Or do readers who always prepare a translation layer between proto and data model classes wish they did not make that decision?

Thank you!
