ES equilibrium problem

Equilibrium of ES
Es two problems: data is evenly distributed (Equilibrium data on) a uniform distribution request processing node (Equilibrium computing resources such as a CPU, i.e. equilibrium problem nodes), and nodes of equilibrium slice are two evaluation equilibrium es dimensions of
handling these two issues, the basic problem of equalization es guaranteed
data distribution is one thing, the data (heat data) often require processing request is a further problem to see the distribution of data
on how the heat distribution is not data uniform, then the request of the uniform how to ensure that, as long as the data is not distributed evenly, you can ensure that each node in the cluster request processing is also uniform it? Or in other words whether the requested data distribution determines the uniform distribution of it?
