Are there any code samples of consumer that is used in production? I'm
looking for a something that is a daemon that has x number of threads and
reads messages of kafka.
I've looked at the sampleconsumer etc., but those are just one of runs that
i'm guessing that you would also have some retries in case a connection
temporarily goes down, and maybe even some co-ordination with zookeeper
etc. to spin up multiple consumers.
