Utilities you'll care about

All these are already installed on epyc.

kafkacat (conda install -c conda-forge kafkacat)
kt (grab it from https://github.com/fgeller/kt/releases)
kafka-* (come with kafka, if you yum install if from Confluent's repo, or via Docker if you're so inclined). Warning -- JVM based and dreadfully slow.
jq (conda install -c conda-forge jq or use your favorite package manager)
