This is part of my Cassandra learning series.
I did stop developing this part as I had enough to the RHEL/Centos changes that happened a few years ago (they made RHEL closed sourced and (I think) had to archive the Centos channels). This meant additional updates to the yum update repos, which, I will get round to doing. But I’m trying my best to get to the database part (Cassandra, Kafka, beats, log stash etc) and not so much faff with flavours of Linux.
