Can someone clarify the usage and requirements of consumer ID when used/specified?
I came across this topic and brought that up in a comment in the thread, someone else suggested it being worthy of another post https://stackoverflow.com/questions/34550873/difference-between-groupid-and-consumerid-in-kafka-consumer/34553058?noredirect=1#comment93322228_34553058 To summarize w/o going to that post/link: Reading the documentation, for consumer.id, description states "Generated automatically if not set." I assume this probably means if manually set, consumer.id should be unique for each consumer? Curious to wonder what happens if you reuse the consumer ID across consumers (like how one shares the consumer group ID) - problems arise or it will work fine but just messy for tracking/debugging active consumers in the group?
