liubao created SCB-2773:
---------------------------

             Summary: Change mutil dicovery registry instance merge policy 
                 Key: SCB-2773
                 URL: https://issues.apache.org/jira/browse/SCB-2773
             Project: Apache ServiceComb
          Issue Type: Improvement
          Components: Java-Chassis
            Reporter: liubao
            Assignee: liubao
             Fix For: java-chassis-3.0.0, java-chassis-2.9.0


Before:

   merge all instances from different discoveries together. 

 

  Problem: Discovery implementation has different revision mechanism, we can not know when revision should updated.

 

After:

   By default, find instances from discovery implementations by order, if find, return the first, or find next. 

   And add a configuration `servicecomb.service.registry.preferred.\{service-name}`  to find only the registry implementation.
