Method Details

seek

void seek(String topic,
 int partition,
 long offset)

Perform a seek operation. When called from ConsumerSeekAware.onPartitionsAssigned(Map, ConsumerSeekCallback) or from ConsumerSeekAware.onIdleContainer(Map, ConsumerSeekCallback) perform the seek immediately on the consumer. When called from elsewhere, queue the seek operation to the consumer. The queued seek will occur after any pending offset commits. The consumer must be currently assigned the specified partition.

Parameters:

topic - the topic.

partition - the partition.

offset - the offset (absolute).

seekToBeginning

void seekToBeginning(String topic,
 int partition)

Perform a seek to beginning operation. When called from ConsumerSeekAware.onPartitionsAssigned(Map, ConsumerSeekCallback) or from ConsumerSeekAware.onIdleContainer(Map, ConsumerSeekCallback) perform the seek immediately on the consumer. When called from elsewhere, queue the seek operation to the consumer. The queued seek will occur after any pending offset commits. The consumer must be currently assigned the specified partition.

Parameters:

topic - the topic.

partition - the partition.

seekToBeginning

default void seekToBeginning(Collection<org.apache.kafka.common.TopicPartition> partitions)

Perform a seek to beginning operation. When called from ConsumerSeekAware.onPartitionsAssigned(Map, ConsumerSeekCallback) or from ConsumerSeekAware.onIdleContainer(Map, ConsumerSeekCallback) perform the seek immediately on the consumer. When called from elsewhere, queue the seek operation to the consumer for each TopicPartition. The seek will occur after any pending offset commits. The consumer must be currently assigned the specified partition(s).

Parameters:

partitions - the TopicPartitions.

Since:

2.3.4

seekToEnd

void seekToEnd(String topic,
 int partition)

Perform a seek to end operation. When called from ConsumerSeekAware.onPartitionsAssigned(Map, ConsumerSeekCallback) or from ConsumerSeekAware.onIdleContainer(Map, ConsumerSeekCallback) perform the seek immediately on the consumer. When called from elsewhere, queue the seek operation to the consumer. The queued seek will occur after any pending offset commits. The consumer must be currently assigned the specified partition.

Parameters:

topic - the topic.

partition - the partition.

seekToEnd

default void seekToEnd(Collection<org.apache.kafka.common.TopicPartition> partitions)

Perform a seek to end operation. When called from ConsumerSeekAware.onPartitionsAssigned(Map, ConsumerSeekCallback) or from ConsumerSeekAware.onIdleContainer(Map, ConsumerSeekCallback) perform the seek immediately on the consumer. When called from elsewhere, queue the seek operation to the consumer for each TopicPartition. The queued seek(s) will occur after any pending offset commits. The consumer must be currently assigned the specified partition(s).

Parameters:

partitions - the TopicPartitions.

Since:

2.3.4

seekRelative

void seekRelative(String topic,
 int partition,
 long offset,
 boolean toCurrent)

Perform a seek relative to the start, end, or current position. When called from ConsumerSeekAware.onPartitionsAssigned(Map, ConsumerSeekCallback) or from ConsumerSeekAware.onIdleContainer(Map, ConsumerSeekCallback) perform the seek immediately on the consumer. When called from elsewhere, queue the seek operation. The queued seek will occur after any pending offset commits. The consumer must be currently assigned the specified partition.

Parameters:

topic - the topic.

partition - the partition.

offset - the offset; positive values are relative to the start, negative values are relative to the end, unless toCurrent is true.

toCurrent - true for the offset to be relative to the current position rather than the beginning or end.

Since:

2.3

seekToTimestamp

void seekToTimestamp(String topic,
 int partition,
 long timestamp)

Perform a seek to the first offset greater than or equal to the time stamp. When called from ConsumerSeekAware.onPartitionsAssigned(Map, ConsumerSeekCallback) or from ConsumerSeekAware.onIdleContainer(Map, ConsumerSeekCallback) perform the seek immediately on the consumer. When called from elsewhere, queue the seek operation. The queued seek will occur after any pending offset commits. The consumer must be currently assigned the specified partition. Use seekToTimestamp(Collection, long) when seeking multiple partitions because the offset lookup is blocking.

Parameters:

topic - the topic.

partition - the partition.

timestamp - the time stamp.

Since:

2.3

seekToTimestamp

void seekToTimestamp(Collection<org.apache.kafka.common.TopicPartition> topicPartitions,
 long timestamp)

Perform a seek to the first offset greater than or equal to the time stamp. When called from ConsumerSeekAware.onPartitionsAssigned(Map, ConsumerSeekCallback) or from ConsumerSeekAware.onIdleContainer(Map, ConsumerSeekCallback) perform the seek immediately on the consumer. When called from elsewhere, queue the seek operation. The queued seek will occur after any pending offset commits. The consumer must be currently assigned the specified partition.

Parameters:

topicPartitions - the topic/partitions.

timestamp - the time stamp.
