Configuration for the Random Subsetting Load Balancing Policy This policy selects a subset of endpoints and passes them to the child LB policy. It maintains 2 important properties: 1. The policy tries to distribute connections among servers as equally as possible. The higher ``(N_clients*subset_size)/N_servers`` ratio is, the closer the resulting server connection distribution is to uniform. 2. The policy minimizes the amount of connection churn generated during server scale-ups by using rendezvous hashing See the :ref:`load balancing architecture overview<arch_overview_load_balancing_types>` for more information.

  subset_size indicates how many backends every client will be connected to. The value must be greater than 0.

• optional config.cluster.v3.LoadBalancingPolicy child_policy = 2

  The config for the child policy. The value is required.
