Hello, I would like to have the ability to store metadata about topics. This would be very useful as with metadata you could add labels and other pieces of information that would allow to define the purpose of a topic, custom application level properties. This feature will allow application level diagnostic tools and maintenance tools to not need external databases to store such metadata.
I imagine that we could add a simple key value map (String keys and String values) to the topic. These metadata could be set during topic creation and also updated. I would store these metadata on the Metadata service (zookkeeper). Is there any interest or any ongoing effort in this direction? Best regards Enrico
