Example 6 with TopicExistsException

use of org.apache.kafka.common.errors.TopicExistsException in project kafka by apache.

the class TopicAdmin method createOrFindTopics.

/**
 * Attempt to create the topics described by the given definitions, returning all of the names of those topics that
 * were created by this request. Any existing topics with the same name are unchanged, and the names of such topics
 * are excluded from the result.
 * <p>
 * If multiple topic definitions have the same topic name, the last one with that name will be used.
 * <p>
 * Apache Kafka added support for creating topics in 0.10.1.0, so this method works as expected with that and later versions.
 * With brokers older than 0.10.1.0, this method is unable to create topics and always returns an empty set.
 *
 * @param topics the specifications of the topics
 * @return the {@link TopicCreationResponse} with the names of the newly created and existing topics;
 *         never null but possibly empty
 * @throws ConnectException if an error occurs, the operation takes too long, or the thread is interrupted while
 *                          attempting to perform this operation
