The registry center should only store and notify necessary data that needs to be passed between providers and consumers, for example host, port, serialization type, etc.
Non-essential data should stored separately and further enriched, these data usually by offline OPS systems for display purpose.
Solve the "Full GC" problem caused by large scale services and url redundancy when provider list notification were triggered.
Design a new runtime metadata storage structure (or reuse the current URL), properly intact with dynamic configuration center.
