Subject Re: bigger data density with Cassandra 4.0?
Date Mon, 27 Aug 2018 12:05:33 GMT
I believe there are caveats that it will only really help if you're not
using vnodes, or you have a very small cluster, and also internode
encryption is not enabled. Alternatively if you're using JBOD vnodes will
be marginally better, but JBOD is not a great idea (and doesn't guarantee a
massive improvement).
