Method Detail

close

public void close(long duration,
                  java.util.concurrent.TimeUnit unit)

Description copied from class: AdminClient

Close the AdminClient 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 and time unit. 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.

Specified by:

close in class AdminClient

Parameters:

duration - The duration to use for the wait time.

unit - The time unit to use for the wait time.

createTopics

public CreateTopicsResult createTopics(java.util.Collection<NewTopic> newTopics,
                                       CreateTopicsOptions options)

Description copied from class: AdminClient

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, AdminClient.listTopics() and AdminClient.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.

Specified by:

createTopics in class AdminClient

Parameters:

newTopics - The new topics to create.

options - The options to use when creating the new topics.

Returns:

The CreateTopicsResult.

deleteTopics

public DeleteTopicsResult deleteTopics(java.util.Collection<java.lang.String> topicNames,
                                       DeleteTopicsOptions options)

Description copied from class: AdminClient

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, AdminClient#listTopics and AdminClient#describeTopics 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.

Description copied from class: AdminClient

Increase the number of partitions of the topics given as the keys of newPartitions according to the corresponding values. If partitions are increased for a topic that has a key, the partition logic or ordering of the messages will be affected.

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

This operation is supported by brokers with version 1.0.0 or higher.

The following exceptions can be anticipated when calling get() on the futures obtained from the values() method of the returned CreatePartitionsResult

• AuthorizationException if the authenticated user is not authorized to alter the topic
• TimeoutException if the request was not completed in within the given AbstractOptions.timeoutMs().
• ReassignmentInProgressException if a partition reassignment is currently in progress
• BrokerNotAvailableException if the requested NewPartitions.assignments() contain a broker that is currently unavailable.
• InvalidReplicationFactorException if no NewPartitions.assignments() are given and it is impossible for the broker to assign replicas with the topics replication factor.
• Subclasses of KafkaException if the request is invalid in some way.
