Not exactly. You mean one data will be put in four nodes which have 25%? If does, how about two replica?

As > I know, I just have one replica So why do you have installed 4 nodes, not 1? They're for your data to be distributed between 4 nodes with 1 copy on one of them. This is like you have 100% of data and each node will have 25% of the data (random partitioning). Viktor.
