[jira] [Commented] (SCB-1964) make schema discovery to be core process

    [ https://issues.apache.org/jira/browse/SCB-1964?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=17140253#comment-17140253 ] 

liubao commented on SCB-1964:
-----------------------------

Now this feature is optional, and will not put required now. Optional is more flexible to java chassis, and may be in some future can put it required.

>                 URL: https://issues.apache.org/jira/browse/SCB-1964
>             Project: Apache ServiceComb
>          Issue Type: Sub-task
>          Components: Java-Chassis
>            Reporter: liubao
>            Assignee: liubao
>            Priority: Major
>             Fix For: java-chassis-2.1.0

>
> Now schema discovery is implementing Discovery interface. 
> Current schema loading process: load from local, load from remote discovery implementation. 
>  
> Some important scenarios:
>  # when calling to a MicroserviceInstance, can discovery schema from MicroserviceInstance. This can avoid java-chassis constraints that the same version of Microservice instances has the same schema. 
>  # can load schema on demand. Do not to load all instances, and construct schema for the instance itself. When instance schema changes, can notified immediatly.
