what's the proper way to extract DOMAIN information for each instance
from external view?
Hi,
Basically, we want to route traffic based on the location of each instance
and this information is encoded in the DOMAIN field in InstanceConfig.
I am wondering if there is an easy way to get it without sending a request
to ZK for every single instance.

Best regards,

InstanceConfig is typically cached on spectator and updated every time it
changes. You might have to add some additional code to simply fetch the
cached instanceconfig.
