Hi Kafka community, I am hoping to get some feedback and thoughts about broker interceptors.
KIP-42 Added Producer and Consumer interceptors which have provided Kafka users the ability to collect client side metrics and trace the path of individual messages end-to-end. This KIP also mentioned "Adding message interceptor on the broker makes a lot of sense, and will add more detail to monitoring. However, the proposal is to do it later in a separate KIP". One of the motivations for leading with client interceptors was to gain experience and see how useable they are before tackling the server side implementation which would ultimately "allow us to have a more complete/detailed message monitoring". Broker interceptors could also provide more value than just more complete and detailed monitoring such as server side schema validation, so I am curious to learn if anyone in the community has progressed this work; has ideas about other potential server side interceptor uses or has actually implemented something similar.
