> Key: SCB-526
> URL: https://issues.apache.org/jira/browse/SCB-526
> Project: Apache ServiceComb
> Issue Type: Improvement
> Reporter: liubao
> Assignee: liubao
> Priority: Major
>
> Currently, dynamic config is fetched asynchronously, and when users use
> dynamic configuration for following scenario will fail:
> # make some environment, e.g. credentials
> # spring @Value mechanism
> and so on.
>
> When users put these configurations to some dynamic configuration server,
> they can assume server is running OK, and if try to fetch will give the
> correct response.
>
> So it's very useful to fetch configurations once when boot up.
