Were you actually able to get 1ms latency from Kafka? How long does it take an event to enter then exit Kafka?

No. I only had boxes with SATA drives. I don't see how you could get below 1ms latency with spinning disks. You would have to use in-memory queue to get this sort of latency. Secondly, I had Storm consuming off Kafka every millisecond, so in the worst case scenario a message would have to wait one millisecond in the queue anyway. Here's a great article about throughput/latency of Kafka https://engineering.linkedin.com/kafka/benchmarking-apache-k....
