      • close

        public void close​(java.time.Duration timeout)
        Description copied from interface: Admin
        Close the Admin client and release all associated resources.

        The close operation has a grace period during which current operations will be allowed to complete, specified by the given duration. New operations will not be accepted during the grace period. Once the grace period is over, all operations that have not yet been completed will be aborted with a TimeoutException.

        Parameters:
        timeout - The time to use for the wait time.

      • createTopics

        public CreateTopicsResult createTopics​(java.util.Collection<NewTopic> newTopics,
                                       CreateTopicsOptions options)
        Description copied from interface: Admin
        Create a batch of new topics.

        This operation is not transactional so it may succeed for some topics while fail for others.

        It may take several seconds after CreateTopicsResult returns success for all the brokers to become aware that the topics have been created. During this time, Admin.listTopics() and Admin.describeTopics(Collection) may not return information about the new topics.

        This operation is supported by brokers with version 0.10.1.0 or higher. The validateOnly option is supported from version 0.10.2.0.

        Parameters:
        newTopics - The new topics to create.
        options - The options to use when creating the new topics.
        Returns:
        The CreateTopicsResult.

      • deleteTopics

        Description copied from interface: Admin
        Delete a batch of topics.

        This operation is not transactional so it may succeed for some topics while fail for others.

        It may take several seconds after the DeleteTopicsResult returns success for all the brokers to become aware that the topics are gone. During this time, Admin.listTopics() and Admin.describeTopics(Collection) may continue to return information about the deleted topics.

        If delete.topic.enable is false on the brokers, deleteTopics will mark the topics for deletion, but not actually delete them. The futures will return successfully in this case.

        This operation is supported by brokers with version 0.10.1.0 or higher.

        Parameters:
        topicNames - The topic names to delete.
        options - The options to use when deleting the topics.
