Re: [protobuf] Compatibility error on adding sub message type in existing proto file

[Komal Kamble]

Hello Robert, Could you please elaborate on reason of having check for message_removed?  Adding new message doesn’t mean compatibility is lost.  Sent from my iPhone On 04-Dec-2022, at 9:41 AM, Robert Yokota <rayok...@gmail.com> wrote:  Hi, I believe this is coming from the Confluent compatibility checker.  (I work for Confluent.) A forward compatibility check is just a backward compatibility check with the arguments reversed.  Since removing a message is not backward compatible, adding a message is not forward compatible. Hope that helps, Robert On Sun, Dec 4, 2022 at 6:35 AM 'Adam Cozzette' via Protocol Buffers <protobuf@googlegroups.com> wrote: I don't think we maintain any code that returns that kind of error. Do you know where that error is coming from? Is it from some external protobuf compatibility checker?

Can you say more about the error you're getting?

I am using com.github.os72:protoc-jar-maven-plugin:3.11.4 plugin in java module to compile proto files and kafka-protobuf-provider:6.1.6 for ProtobufSchema object.  The query is getting compatibility errors is it correct behavior or not? I didn't find any documentation in protocol-buffer user guide regarding adding more sub-message types in the existing proto file.  Could you please help me to understand the standard behavior of the protocol buffer?  -- You received this message because you are subscribed to the Google Groups "Protocol Buffers" group.
