This article mainly introduces "the creation method of zookeeper data node". In the daily operation, I believe that many people have doubts about the creation method of zookeeper data node. The editor consulted all kinds of materials and sorted out simple and easy-to-use operation methods. I hope it will be helpful to answer the doubts about "the creation method of zookeeper data node". Next, please follow the editor to study!

Data node type

Temporary node

Ordinary temporary node

This type of node is bound to sesssion. If session fails, the node will be cleared, and there can be no child nodes under this node. The related code is as follows:

Client.create () .creatingParentsIfNeutral () / Recursive create .withMode (CreateMode.EPHEMERAL) / / Node Type .forPath (path,data)

Ordered temporary node

The parent of the node must be a persistent node

Client.create () .creatingParentsIfNeutral () .withMode (CreateMode.EPHEMERAL_SEQUENTIAL) .forPath (path); / / path example: "create-order/order-" / / get method: getChildren () .forPath ("create-order")

Persistent node

Ordinary persistent node

Client.create () .creatingParentsIfNeutral () .withMode (CreateMode.PERSISTENT) .forPath (path,data)

Ordered persistent node

Client.create () .creatingParentsIfNeutralization () .withMode (CreateMode.PERSISTENT_SEQUENTIAL) .forPath (path,data); at this point, the study of "how to create zookeeper data nodes" is over, hoping to solve everyone's doubts. The collocation of theory and practice can better help you learn, go and try it! If you want to continue to learn more related knowledge, please continue to follow the website, the editor will continue to work hard to bring you more practical articles!
