Hi all, I was wondering if there is any benchmark or any recommendation for having physical HW vs virtual for the Kafka Brokers. I am trying to calculate the HW requirements for a Kafka Cluster with a hard SLA. My questions are as follows.
- What is the effect of OS disk caching for a Kafka-Broker? How much on-heap and off-heap memory would be required per node? - Since Kafka read-write workload is pretty sequential which of the following spinning disks would be recommended? SATA 7.2k, SAS 10k, SAS 15k? - Since Kafka is not CPU-intensive, how bad would be to coexist Kafka-Broker and a CPU-intensive workload like STORM? Regards, Ali
