> * 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.
