Class CreateClusterLinkPolicy

java.lang.Object

io.confluent.kafka.server.plugins.policy.CreateClusterLinkPolicy

All Implemented Interfaces:

org.apache.kafka.common.Configurable, org.apache.kafka.common.Reconfigurable, org.apache.kafka.server.interceptor.ClusterLinkInterceptor, org.apache.kafka.server.policy.CreateClusterLinkPolicy

public class CreateClusterLinkPolicy
extends Object
implements org.apache.kafka.server.policy.CreateClusterLinkPolicy, org.apache.kafka.server.interceptor.ClusterLinkInterceptor, org.apache.kafka.common.Reconfigurable

Enforce the policy when creating the cluster links, for example enforcing maximum number of cluster links per tenant. Even though validate(), linkAdded() and linkDeleted() are thread-safe, clients should execute validate() and linkAdded() atomically so that the number of links won't exceed the limit.
