What i've got to set up my Apache Cassandra cluster are some Servers with 20 Core cpu * 2 Threads and 128 GB ram and 8 * 2TB disk.
Just read all over the web: Do not use big nodes for your cluster, i'm convinced to run multiple nodes on a single physical server. So the question is which technology should i use: Docker or Virtualiztion (ESX)? Any exprience? Sent using Zoho Mail
