Micro Service Discovery Author: Vincent Young Version: v1.0.0
Based: Etcd EtcdKeyRule: /{Prefix}/{SupportService}/{ServiceAddr}
Support: 1. Load Balance Strategy: polling、random 2. Auto find the normal node 3. Multi services 4. Service cluster 5. Optional etcd prefix
TODO: 1. Discover center cluster 2. Etcd value more service info (v1.0.0: Only addr string) 3. Optional service (v1.0.0: Need to hard code in discovery file) 4. Optimize error output 5. Add get all services method, so can implement load balance out of discovery (v1.0.0: Load balance in discovery)
