When Will Modified Weights Take Effect?

The new weights for backend servers take effect immediately after the weights are configured. Connections that have been established with backend servers will not be affected.

If the weight of a backend server is changed to 0, the new weight does not take effect immediately, and requests are still routed to this backend server. This is because a persistent connection is established between the load balancer and the backend server and requests are routed to this server until the connection times out.
