Because I like to write test clients to see how things work... Don't you?
Clone... Build... Run
All clients accept an initial broker as their first argument. If ommitted it will default to 192.168.33.50:9092... #justcoz.
A simple producer that sends timestamps to a topic named perf-test.
A polling consumer that receives timestamps from a topic named perf-test by joining the perf-group consumer group.
A combination of the above 2 that limits to 1000 messages... useful for things like automated performance testing.
