  • Method Details

    • close

      public void close(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(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

      public DeleteTopicsResult deleteTopics(TopicCollection topics, DeleteTopicsOptions options)
      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.

      When using topic IDs, this operation is supported by brokers with inter-broker protocol 2.8 or higher. When using topic names, this operation is supported by brokers with version 0.10.1.0 or higher.

      Parameters:

    • updateFeatures

      public UpdateFeaturesResult updateFeatures(Map<String,FeatureUpdate> featureUpdates, UpdateFeaturesOptions options)
      Description copied from interface: Admin
      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:

      This operation is supported by brokers with version 2.7.0 or higher.

      Parameters:
      featureUpdates - the map of finalized feature name to FeatureUpdate

      • TimeoutException If the request timed out before the describe operation could finish.
      • UnsupportedVersionException If the software is too old to support the unregistration API, or if the cluster is not using Raft to store metadata.

      Parameters:
      brokerId - the broker id to unregister.
      options - the options to use.
      Returns:
      the UnregisterBrokerResult containing the result

    • describeProducers

      public DescribeProducersResult describeProducers(Collection<TopicPartition> topicPartitions, DescribeProducersOptions options)
      Description copied from interface: Admin
      Describe active producer state on a set of topic partitions. Unless a specific broker is requested through DescribeProducersOptions.brokerId(int), this will query the partition leader to find the producer state.
      Parameters:
      topicPartitions - The set of partitions to query
      options - Options to control the method behavior
      Returns:
      The result

    • describeTransactions

      public DescribeTransactionsResult describeTransactions(Collection<String> transactionalIds, DescribeTransactionsOptions options)
      Description copied from interface: Admin
      Describe the state of a set of transactional IDs from the respective transaction coordinators, which are dynamically discovered.
      Parameters:
      transactionalIds - The set of transactional IDs to query
      options - Options to control the method behavior
      Returns:
      The result

    • abortTransaction

      public AbortTransactionResult abortTransaction(AbortTransactionSpec spec, AbortTransactionOptions options)
      Description copied from interface: Admin
      Forcefully abort a transaction which is open on a topic partition. This will send a `WriteTxnMarkers` request to the partition leader in order to abort the transaction. This requires administrative privileges.
      Parameters:
      spec - The transaction specification including topic partition and producer details
      options - Options to control the method behavior (including filters)
      Returns:
      The result

    • listTransactions

      public ListTransactionsResult listTransactions(ListTransactionsOptions options)
      Description copied from interface: Admin
      List active transactions in the cluster. This will query all potential transaction coordinators in the cluster and collect the state of all transactions. Users should typically attempt to reduce the size of the result set using ListTransactionsOptions.filterProducerIds(Collection) or ListTransactionsOptions.filterStates(Collection)
      Parameters:
      options - Options to control the method behavior (including filters)
      Returns:
      The result

    • fenceProducers

      public FenceProducersResult fenceProducers(Collection<String> transactionalIds, FenceProducersOptions options)
      Description copied from interface: Admin
      Fence out all active producers that use any of the provided transactional IDs.
      Parameters:
      transactionalIds - The IDs of the producers to fence.
      options - The options to use when fencing the producers.
      Returns:
      The FenceProducersResult.

    • listClientMetricsResources

      public ListClientMetricsResourcesResult listClientMetricsResources(ListClientMetricsResourcesOptions options)
      Description copied from interface: Admin
      List the client metrics configuration resources available in the cluster.
      Parameters:
      options - The options to use when listing the client metrics resources.
      Returns:
      The ListClientMetricsResourcesResult.

    • clientInstanceId

      public Uuid clientInstanceId(Duration timeout)
      Description copied from interface: Admin
      Determines the client's unique client instance ID used for telemetry. This ID is unique to this specific client instance and will not change after it is initially generated. The ID is useful for correlating client operations with telemetry sent to the broker and to its eventual monitoring destinations.

      If telemetry is enabled, this will first require a connection to the cluster to generate the unique client instance ID. This method waits up to timeout for the admin client to complete the request.

      Client telemetry is controlled by the AdminClientConfig.ENABLE_METRICS_PUSH_CONFIG configuration option.

      Parameters:
      timeout - The maximum time to wait for admin client to determine its client instance ID. The value must be non-negative. Specifying a timeout of zero means do not wait for the initial request to complete if it hasn't already.
      Returns:
      The client's assigned instance id used for metrics collection.
