Class RuleBasedZooKeeperAclProvider

java.lang.Object

com.spotify.helios.servicescommon.RuleBasedZooKeeperAclProvider

All Implemented Interfaces:

org.apache.curator.framework.api.ACLProvider, org.apache.curator.utils.InternalACLProvider

public class RuleBasedZooKeeperAclProvider
extends Object
implements org.apache.curator.framework.api.ACLProvider

A ZooKeeper ACLProvider that uses regular expression-based rules to determine what ACLs govern created nodes.

The permissions for all rules that match a path apply. For example if there are two rules:

1. "/foo.*", DELETE, usr1
2. "/foo/bar", CREATE, user1

Then ACLs will be set so that user1 can create and delete nodes on the /foo/bar node, but he can not delete nodes under the /foo node.
