Example 1 with CreatableTopicConfigs

use of org.apache.kafka.common.message.CreateTopicsResponseData.CreatableTopicConfigs in project kafka by apache.

the class RequestResponseTest method createCreateTopicResponse.

private CreateTopicsResponse createCreateTopicResponse() {
    CreateTopicsResponseData data = new CreateTopicsResponseData();
    data.topics().add(new CreatableTopicResult().setName("t1").setErrorCode(Errors.INVALID_TOPIC_EXCEPTION.code()).setErrorMessage(null));

    data.topics().add(new CreatableTopicResult().setName("t3").setErrorCode(Errors.NONE.code()).setNumPartitions(1).setReplicationFactor((short) 2).setConfigs(singletonList(new CreatableTopicConfigs().setName("min.insync.replicas").setValue("2"))));
