The Google Protocol Buffers are a way of encoding structured data in an efficient — yet, extensible — format. It’s a richer and better alternative to Java serialization.

I strongly recommend experienced Java developers to learn Google Protobuf. You can see this article to learn more about the Google Protocol Buffer.

And, if you need a resource to learn Google Protocol Buffer then I highly recommend you to join Complete Guide to Protocol Buffers 3 [Java, Golang, Python] course by

on Udemy. It’s a really nice and up-to-date resource to learn Google Protocol buffer.
