```
@InterfaceStability.Evolving
public interface Admin
extends AutoCloseable
```
The administrative client for Kafka, which supports managing and inspecting topics, brokers, configurations and ACLs.
Instances returned from the create methods of this interface are guaranteed to be thread safe. However, the KafkaFutures returned from request methods are executed by a single thread so it is important that any code which executes on that thread when they complete (using KafkaFuture.thenApply(KafkaFuture.Function), for example) doesn't block for too long. If necessary, processing of results should be passed to another thread.
The operations exposed by Admin follow a consistent pattern:
- Admin instances should be created using create(Properties) or create(Map)
- Each operation typically has two overloaded methods, one which uses a default set of options and an overloaded method where the last parameter is an explicit options object.
- The operation method's first parameter is a Collection of items to perform the operation on. Batching multiple requests into a single call is more efficient and should be preferred over multiple calls to the same method.
- The operation methods execute asynchronously.
- Each xxx operation method returns an XxxResult class with methods which expose KafkaFuture for accessing the result(s) of the operation.
- Typically an all() method is provided for getting the overall success/failure of the batch and a values() method provided access to each item in a request batch. Other methods may also be provided.
- For synchronous behaviour use KafkaFuture.get()
Here is a simple example of using an Admin client instance to create a new topic:
```
 
 Properties props = new Properties();
 props.put(AdminClientConfig.BOOTSTRAP_SERVERS_CONFIG, "localhost:9092");

 try (Admin admin = Admin.create(props)) {
   String topicName = "my-topic";
   int partitions = 12;
   short replicationFactor = 3;
   // Create a compacted topic
   CreateTopicsResult result = admin.createTopics(Collections.singleton(
     new NewTopic(topicName, partitions, replicationFactor)
       .configs(Collections.singletonMap(TopicConfig.CLEANUP_POLICY_CONFIG, TopicConfig.CLEANUP_POLICY_COMPACT))));

   // Call values() to get the result for a specific topic
   KafkaFuture<Void> future = result.values().get(topicName);

   // Call get() to block until the topic creation is complete or has failed
   // if creation failed the ExecutionException wraps the underlying cause.
   future.get();
 }
 
 
```
Bootstrap and balancing

The bootstrap.servers config in the Map or Properties passed to create(Properties) is only used for discovering the brokers in the cluster, which the client will then connect to as needed. As such, it is sufficient to include only two or three broker addresses to cope with the possibility of brokers being unavailable.
Different operations necessitate requests being sent to different nodes in the cluster. For example createTopics(Collection) communicates with the controller, but describeTopics(Collection) can talk to any broker. When the recipient does not matter the instance will try to use the broker with the fewest outstanding requests.
The client will transparently retry certain errors which are usually transient. For example if the request for createTopics() get sent to a node which was not the controller the metadata would be refreshed and the request re-sent to the controller.
Broker Compatibility

The minimum broker version required is 0.10.0.0. Methods with stricter requirements will specify the minimum broker version required.
This client was introduced in 0.11.0.0 and the API is still evolving. We will try to evolve the API in a compatible manner, but we reserve the right to make breaking changes in minor releases, if necessary. We will update the InterfaceStability annotation and this notice once the API is considered stable.

    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:

  - createTopics
```

    This operation is not transactional so it may succeed for some partitions while fail for others.
    It may take several seconds after this method returns success for all the brokers in the cluster to become aware that the partitions have new leaders. During this time, describeTopics(Collection) may not return information about the partitions' new leaders.
    This operation is supported by brokers with version 2.2.0 or later if preferred election is use; otherwise the brokers most be 2.4.0 or higher.
    The following exceptions can be anticipated when calling get() on the future obtained from the returned ElectLeadersResult:
    - ClusterAuthorizationException if the authenticated user didn't have alter access to the cluster.
    - UnknownTopicOrPartitionException if the topic or partition did not exist within the cluster.
    - InvalidTopicException if the topic was already queued for deletion.
    - NotControllerException if the request was sent to a broker that was not the controller for the cluster.
    - TimeoutException if the request timed out before the election was complete.
    - LeaderNotAvailableException if the preferred leader was not alive or not in the ISR.
    Parameters:
    
    electionType - The type of election to conduct.
    
    partitions - The topics and partitions for which to conduct elections.
    
    options - The options to use when electing the leaders.
    
    Returns:
    
    The ElectLeadersResult.

                                    UpdateFeaturesOptions options)
```
    Applies specified updates to finalized features. This operation is not transactional so some updates may succeed while the rest may fail.
    The API takes in a map of finalized feature names to FeatureUpdate that needs to be applied. Each entry in the map specifies the finalized feature to be added or updated or deleted, along with the new max feature version level value. This request is issued only to the controller since the API is only served by the controller. The return value contains an error code for each supplied FeatureUpdate, and the code indicates if the update succeeded or failed in the controller.
    - Downgrade of feature version level is not a regular operation/intent. It is only allowed in the controller if the FeatureUpdate has the allowDowngrade flag set. Setting this flag conveys user intent to attempt downgrade of a feature max version level. Note that despite the allowDowngrade flag being set, certain downgrades may be rejected by the controller if it is deemed impossible.
    - Deletion of a finalized feature version is not a regular operation/intent. It could be done by setting the allowDowngrade flag to true in the FeatureUpdate, and, setting the max version level to a value less than 1.
    The following exceptions can be anticipated when calling get() on the futures obtained from the returned UpdateFeaturesResult:
    - ClusterAuthorizationException If the authenticated user didn't have alter access to the cluster.
    - InvalidRequestException If the request details are invalid. e.g., a non-existing finalized feature is attempted to be deleted or downgraded.
    - TimeoutException If the request timed out before the updates could finish. It cannot be guaranteed whether the updates succeeded or not.
    - FeatureUpdateFailedException This means there was an unexpected error encountered when the update was applied on the controller. There is no guarantee on whether the update succeeded or failed. The best way to find out is to issue a describeFeatures(DescribeFeaturesOptions) request.
    This operation is supported by brokers with version 2.7.0 or higher.
    Parameters:
    
    featureUpdates - the map of finalized feature name to FeatureUpdate
    
    options - the options to use
    
    Returns:
    
    the UpdateFeaturesResult containing the result
