Date Fri, 09 Mar 2018 04:48:04 GMT
Support unit router feature for dubbo, new feature pr: https://github.com/alibaba/dubbo/pull/1438

What problems can this feature solve?

case 1:
If we have two instance of services or more, we call it serviceA(, serviceA(

We want to invoke serviceA ( first, if serviceA ( is not available
then invoke serviceA ( automatically.

case 2:

If we have many relative services, We call it serviceA(, serviceA(,
serviceB(, serviceB(, serviceC(, serviceC(

dependencies of service:
serviceA -> serviceB -> serviceC
We can flexibly build call paths and automatically downgrade calls.
