subsetSize

The number of backends per backend group assigned to each proxy instance or each service mesh client. An input parameter to the CONSISTENT_HASH_SUBSETTING algorithm. Can only be set if policy is set to CONSISTENT_HASH_SUBSETTING. Can only be set if load balancing scheme is INTERNAL_MANAGED or INTERNAL_SELF_MANAGED. subset_size is optional for Internal HTTP(S) load balancing and required for Traffic Director. If you do not provide this value, Cloud Load Balancing will calculate it dynamically to optimize the number of proxies/clients visible to each backend and vice versa. Must be greater than 0. If subset_size is larger than the number of backends/endpoints, then subsetting is disabled.
