title: How much total virtual cores are required to process 100GB of data in spark
body: <p>For example if i choose 16 vcore with 10 worker nodes, so 16-1 (one core to store the hadoop daemons) * 10 (worker nodes) = 150 vcores (Total).
  Is it safe to say that 150 vcores are required to process 100GB of data?
  or is there any calculation should i need to consider before choosing the vcore?</p>
