类 NoStoppingOffsetsInitializer

java.lang.Object

org.apache.flink.connector.kafka.source.enumerator.initializer.NoStoppingOffsetsInitializer

所有已实现的接口:

Serializable, OffsetsInitializer

@Internal
public class NoStoppingOffsetsInitializer
extends Object
implements OffsetsInitializer

An implementation of OffsetsInitializer which does not initialize anything.

This class is used as the default stopping offsets initializer for unbounded Kafka sources.

getPartitionOffsets

public Map<org.apache.kafka.common.TopicPartition,Long> getPartitionOffsets(Collection<org.apache.kafka.common.TopicPartition> partitions,
                                                                            OffsetsInitializer.PartitionOffsetsRetriever partitionOffsetsRetriever)

从接口复制的说明: OffsetsInitializer

Get the initial offsets for the given Kafka partitions. These offsets will be used as either starting offsets or stopping offsets of the Kafka partitions.

If the implementation returns a starting offset which causes OffsetsOutOfRangeException from Kafka. The OffsetResetStrategy provided by the OffsetsInitializer.getAutoOffsetResetStrategy() will be used to reset the offset.

指定者:

getPartitionOffsets 在接口中 OffsetsInitializer

参数:

partitions - the Kafka partitions to get the starting offsets.

partitionOffsetsRetriever - a helper to retrieve information of the Kafka partitions.

返回:

A mapping from Kafka partition to their offsets to start consuming from.

getAutoOffsetResetStrategy

public org.apache.kafka.clients.consumer.OffsetResetStrategy getAutoOffsetResetStrategy()

从接口复制的说明: OffsetsInitializer

Get the auto offset reset strategy in case the initialized offsets falls out of the range.

The OffsetStrategy is only used when the offset initializer is used to initialize the starting offsets and the starting offsets is out of range.

指定者:

getAutoOffsetResetStrategy 在接口中 OffsetsInitializer

返回:

An OffsetResetStrategy to use if the initialized offsets are out of the range.
