Example 1 with CreatePartitionsResult

use of org.apache.kafka.clients.admin.CreatePartitionsResult in project strimzi by strimzi.

the class ControllerIT method alterTopicNumPartitions.

private void alterTopicNumPartitions(TestContext context, String topicName, String configMapName) throws InterruptedException, ExecutionException {
    int changedValue = 2;
    NewPartitions newPartitions = NewPartitions.increaseTo(changedValue);
    Map<String, NewPartitions> map = new HashMap<>(1);

    }, timeout, "Expected the configmap to have been deleted by now");
}

Example 2 with CreatePartitionsResult

use of org.apache.kafka.clients.admin.CreatePartitionsResult in project druid by druid-io.

the class KafkaAdminClient method updatePartitionCount.

/**
 * This method can only increase the partition count of {@param streamName} to have a final partition
 * count of {@param newPartitionCount}
 * If {@param blocksUntilStarted} is set to true, then this method will blocks until the partitioning
 * started (but not nessesary finished), otherwise, the method will returns right after issue the
 * repartitioning command

public void updatePartitionCount(String streamName, int newPartitionCount, boolean blocksUntilStarted) throws Exception {
    Map<String, NewPartitions> counts = new HashMap<>();
    counts.put(streamName, NewPartitions.increaseTo(newPartitionCount));
    CreatePartitionsResult createPartitionsResult = adminClient.createPartitions(counts);
    if (blocksUntilStarted) {
        createPartitionsResult.values().get(streamName).get();
    }
