I have deployed a go application in kubernetes. My application has a go routine which continuously listens for messages from a kafka topic and push new messages into a go channel for further processing and commits kafka message. If I scale down the number of replicas using hpa/if replica goes down due to panic, what happens to the messages which are still in go channel unprocessed?

5If a process dies, all the memory that it used is usually reclaimed by the OS. – super Feb 10 '22 at 11:19

Have you ever brought this up or is it a hypothetical example? – Mikołaj Głodziak Feb 10 '22 at 14:28

The channels in go are in the memory, so when the app crashes, everything in the channels will be lost.
