The logic has been improved from multi (node->partition) to one (partition).
The partition with too much nodes has been improved already.

> In above logic, if we have thousands of node in one partition, we will still
> repeatedly access all nodes of the partition thousands of times. There is no
> break point where if the partition is not same for the first node, it should
> stop checking other nodes in that partition.
