Clustering questions


1.What is a Edge Node?
2. Where will Local memory present in Cluster Physically ? and on which node ?
3. what are the average RAM sizes of all Master Nodes and Slave nodes and Edge Node in Cluster ?



It would be more useful, if you can ask specific questions. Like instead of asking what is a edge node, tell what aspect you are not clear about? Also, provide some context, where have you read the terms and in what situation.

That will make these questions more meaningful.
