Architecture HighLights

  • All registration information will be stored in NacosSync DB.
  • Multiple NacosSync instances will perform the same job.
    • Multiple NacosSync instances ensure high availability.
    • Multiple NacosSync instances performing the same job ensure the simplicity.
    • NacosCluster target will dedup the synchronization information from Nacos.

Task remains (for 虎牙 Project):

  • 数据库，增加字段，增加task_type, 比如 nacos-> nacos, or dubbo_zk -> nacos. 目前仅支持内部ConfigServer->Nacos
  • 代码逻辑抽象，要吧现在的 SyncManagerService 改下，区分开不同的任务类型用不同的同步方式
  • Console, 还未实现，目前用户只能通过API来访问：http://127.0.0.1:8081/skywalker/swagger-ui.html#/
  • 重构代码，以NacosSync替换Skywalker，并去掉阿里内部特有的Driver，如数据库Driver。
