In this case, all physical databases matched with the name are traversed according is to automat‐ ically balance between the resource control and the execution efficiency. Connection Mode From the perspective of resource control, the connection number of the business side’s visit can be used, under this kind of circumstances, it will also degenerate to the memory merger.

In this regard, we use the cluster topology state diagram to manage to achieve configuration synchronization, notification of state changes and distributed locks to control exclusive operations. At the same time, since the governance function itself can use appropriate
