Constructor Details

PartitionState

public PartitionState(org.apache.kafka.common.TopicPartition tp, OffsetMapCodecManager.HighestOffsetAndIncompletes offsetData)

Method Details

onOffsetCommitSuccess

public void onOffsetCommitSuccess(org.apache.kafka.clients.consumer.OffsetAndMetadata committed)

isRecordPreviouslyCompleted

public boolean isRecordPreviouslyCompleted(org.apache.kafka.clients.consumer.ConsumerRecord<K,V> rec)

hasWorkInCommitQueue

public boolean hasWorkInCommitQueue()

getCommitQueueSize

public int getCommitQueueSize()

onSuccess

public void onSuccess(WorkContainer<K,V> work)

onFailure

public void onFailure(WorkContainer<K,V> work)

addWorkContainer

public void addWorkContainer(WorkContainer<K,V> wc)

isRemoved

public boolean isRemoved()

Has this partition been removed? No.

Returns:

by definition false in this implementation

getCommitDataIfDirty

public Optional<org.apache.kafka.clients.consumer.OffsetAndMetadata> getCommitDataIfDirty()

getAllIncompleteOffsets

public Set<Long> getAllIncompleteOffsets()

Returns:

all incomplete offsets of buffered work in this shard, even if higher than the highest succeeded

getIncompleteOffsetsBelowHighestSucceeded

public Set<Long> getIncompleteOffsetsBelowHighestSucceeded()

Returns:

incomplete offsets which are lower than the highest succeeded

getOffsetHighestSequentialSucceeded

public long getOffsetHighestSequentialSucceeded()

onPartitionsRemoved

public void onPartitionsRemoved(ShardManager<K,V> sm)

isBlocked

public boolean isBlocked()

Convenience method for readability

Returns:

true if isAllowedMoreRecords() is false

See Also:

isAllowedMoreRecords()

toString

public String toString()

Overrides:

toString in class Object

getTp

public org.apache.kafka.common.TopicPartition getTp()

getOffsetHighestSeen

public long getOffsetHighestSeen()

The highest seen offset for a partition.

Starts off as -1 - no data. Offsets in Kafka are never negative, so this is fine.

getOffsetHighestSucceeded

public long getOffsetHighestSucceeded()

Highest offset which has completed successfully ("succeeded").
