   > Thanks for sharing the details, @GabrielCWT ! That sounds like a 
reasonable use case.

   > My only concern was with adding a new type of free-form info to 
`DruidNode` since it is primarily used for service discovery. There can be 
issues with Zookeeper if a node ends up having very large label values, but I 
suppose it is not very likely to happen and would be a configuration issue 
rather than a code issue anyway.

wouldn't be able to display it on the web-console.
   
   I think it's better to show the label in the web console. Another use case 
is that we can inject some container meta data like container name to this 
property when druid is deployed in K8s, so that we know which service/host maps 
to which container from web-console
