Method Details

waitForTopic

public static void waitForTopic(String topic,
 int numPartitions,
 org.apache.kafka.common.utils.Time time,
 Duration timeout,
 Function<String, Set<Integer>> describeTopic,
 Consumer<String> createTopic)

Waits for full partition metadata for topic with `numPartitions` partitions to be available. This method handles edge cases where partial metadata for a topic may be available on the broker.

Parameters:

topic - Name of topic to wait for

numPartitions - Expected number of partitions

time - Instance of time used for timeout

timeout - Timeout duration

describeTopic - Topic describe function that returns set of partitions returned from a metadata request. Returned set may be empty.

createTopic - Function used to create topic. If null, topic is not created and this method just waits for topic to be available.

Throws:

IllegalStateException - if the actual number of partitions exceeds `numPartitions`

org.apache.kafka.common.errors.TimeoutException - if partition metadata for all of `numPartitions` partitions are not available within timeout

org.apache.kafka.common.KafkaException - if describe or create fails with an non-retriable exception
