Types ¶
type ApolloLoader ¶
type ApolloLoader struct {

ApolloAppId string // apollo app id
PropertyNames []string // property names to search for rule parameters, the first one with non-empty value will be effective.
}
* apollo(https://github.com/apolloconfig/apollo) is a configuration management system. This loader load rule parameters from the application namespace of a given apollo app id.
rule parameters are encoded with format '<key>=<value>;<key>=<value>...'(e.g. 'xmx=quota-512;gc=auto;nmt=off').
