# Zookeeper Registry Server
-[Zookeeper](http://zookeeper.apache.org) is the child project of apache hadoop. Since it offers tree-like directory service and supports change notification, it's suitable to use it as dubbo's registry server. It's a field-proven product, therefore it's recommended to use it in the production environment. [^1]

Description on registration procedure:
* When service provider boots up: write service URL address under directory `/dubbo/com.foo.BarService/providers`
-* When service consumer boots up: subscribe to `/dubbo/com.foo.BarService/providers` for provider's URL addresses. At the same time, write consumer's URL address under `/dubbo/com.foo.BarService/providers`.
+* When service consumer boots up: subscribe to `/dubbo/com.foo.BarService/providers` for provider's URL addresses. At the same time, write consumer's URL address under `/dubbo/com.foo.BarService/consumers`.
Review comment:
The prefix for writing the key is obtained by reading the group attribute. eg: `/dubbo/com.foo.BarService/providers` , for example, the service group is test, the key is changed to '/test/com.foo.BarService/providers' or '/test/com.foo.BarService/consumers'.
