discoverLocalMetadata
Description copied from interface:DiscoveryStrategy
Returns a map with discovered metadata provided by the runtime environment. Those information may include, but are not limited, to location information like datacenter, rack, host, node name or additional tags to be used for custom purpose.Information discovered from this method are shaded into the
Member
s attributes. Existing attributes will not be overridden, that way local attribute configuration overrides provided metadata.The default implementation provides an empty map with no further metadata configured. Returning
null
is not permitted and will most probably result in anNullPointerException
