Jun Liu created DUBBO-19:
Summary: Metadata refactor
Project: Apache Dubbo
Issue Type: Improvement
Reporter: Jun Liu
* 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.
