We need the @Internal annotation for cases where a user-facing class has methods entirely meant for internal uses. It's not great that we have these cases to being with, but fixing that is another story. The semantics for non-annotated classes is already documented. https://nightlies.apache.org

Hi Shammon, Thanks for asking. @PublicEvolving is actually a very useful design that developers can offer APIs as publicly accessible but still have changes to introduce modifications afterwards between minor releases. Compared to it, all @Public APIs can only be changed between major releases. Be

Thanks Jing for starting this discussion. For @Becket > 1. All the public methods / classes / interfaces MUST be annotated with one of the @Experimental / @PublicEvolving / @Public. In practice, all the methods by default inherit the annotation from the containing class, unless annotated otherwise

Hi devs, While I was joining the flink-avro enhancement and cleanup discussion driven by Becket[1], I realized that there are some issues with the current Flink API annotation usage in the source code. As far as I am concerned, Flink wants to control the access/visibility of APIs across modules a
