UNDEFINED_POLICY (0):
A value indicating that the enum field is not
set.
CONSISTENT_HASH_SUBSETTING (108989492):
Subsetting based on consistent hashing. For Traffic
Director, the number of backends per backend group (the
subset size) is based on the subset_size parameter. For
Internal HTTP(S) load balancing, the number of backends per
backend group (the subset size) is dynamically adjusted in
two cases: - As the number of proxy instances participating
in Internal HTTP(S) load balancing increases, the subset
size decreases. - When the total number of backends in a
network exceeds the capacity of a single proxy instance,
subset sizes are reduced automatically for each service that
has backend subsetting enabled.
NONE (2402104):
No Subsetting. Clients may open connections
and send traffic to all backends of this backend
service. This can lead to performance issues if
there is substantial imbalance in the count of
clients and backends.
