maoling commented on ZOOKEEPER-3167: ------------------------------------ [~TyqITstudent] Zookeeper uses the github workflow.The contributor guide is [here](https://cwiki.apache.org/confluence/display/ZOOKEEPER/HowToContribute]) > add an API to get total count of recursive sub nodes of one node > ---------------------------------------------------------------- > > Key: ZOOKEEPER-3167 > URL: https://issues.apache.org/jira/browse/ZOOKEEPER-3167 > Project: ZooKeeper > Issue Type: New Feature > Affects Versions: 3.4.5, 3.5.0 > Reporter: 田毅群 > Priority: Minor > Labels: patch > Fix For: 3.4.5 > > Attachments: 0001-add-get-recursive-children-node-api.patch > > > 1. In production environment, there will be always a situation that there are > a lot of recursive sub nodes of one node. We need to count total number of it. > 2. Now, we can only use API getChildren which returns the List<String> of > first level of sub nodes. We need to iterate every sub node to get recursive > sub nodes. It will cost a lot of time. > 3. In zookeeper server side, it uses Hasp<String, DataNode> to store node. > The key of the map represents the path of the node. We can iterate the map > get total number of all levels of sub nodes of one node. -- This message was sent by Atlassian JIRA (v7.6.3#76005)
