Likewise, if a node becomes overwhelmed, the load balance will move a primary replica to another node that has less load.
同样，如果节点过载，负载均衡就会从主副本转移到另一个负载较少的节点上。

Load balance strategies is used to improve the utilization of each node in the system, but it will lead to more system overhead if we pursue absolute balance of system load.
采用负载平衡策略的目的是为了改进系统中各结点的利用率，追求系统负载的绝对平衡会造成系统开销的增大。

As the complement of early replication, the instant replication is used to balance load between nodes with the source node reserves more resource to server the local user.
