Abstract Value Members

abstract def commitOffsets(offsetsToCommit: Map[TopicAndPartition, OffsetAndMetadata], retryOnFailure: Boolean): Unit

Commit offsets from an external offsets map.
Commit offsets from an external offsets map.
offsetsToCommit
the offsets to be committed.
abstract def commitOffsets: Unit

KAFKA-1743: This method added for backward compatibility.
abstract def commitOffsets(retryOnFailure: Boolean): Unit

Commit the offsets of all broker partitions connected by this connector.
abstract def createMessageStreams[K, V](topicCountMap: Map[String, Int], keyDecoder: Decoder[K], valueDecoder: Decoder[V]): Map[String, List[KafkaStream[K, V]]]

Create a list of MessageStreams for each topic.
Create a list of MessageStreams for each topic.
topicCountMap
a map of (topic, #streams) pair
keyDecoder
Decoder to decode the key portion of the message
valueDecoder
Decoder to decode the value portion of the message
returns
a map of (topic, list of KafkaStream) pairs. The number of items in the list is #streams. Each stream supports an iterator over message/metadata pairs.
abstract def createMessageStreams(topicCountMap: Map[String, Int]): Map[String, List[KafkaStream[Array[Byte], Array[Byte]]]]

Create a list of MessageStreams for each topic.
Create a list of MessageStreams for each topic.
topicCountMap
a map of (topic, #streams) pair
returns
a map of (topic, list of KafkaStream) pairs. The number of items in the list is #streams. Each stream supports an iterator over message/metadata pairs.
abstract def createMessageStreamsByFilter[K, V](topicFilter: TopicFilter, numStreams: Int = 1, keyDecoder: Decoder[K] = new DefaultDecoder(), valueDecoder: Decoder[V] = new DefaultDecoder()): Seq[KafkaStream[K, V]]

Create a list of message streams for all topics that match a given filter.
Create a list of message streams for all topics that match a given filter.
topicFilter
Either a Whitelist or Blacklist TopicFilter object.
numStreams
Number of streams to return
keyDecoder
Decoder to decode the key portion of the message
valueDecoder
Decoder to decode the value portion of the message
returns
a list of KafkaStream each of which provides an iterator over message/metadata pairs over allowed topics.
abstract def setConsumerRebalanceListener(listener: ConsumerRebalanceListener): Unit

Wire in a consumer rebalance listener to be executed when consumer rebalance occurs.
Wire in a consumer rebalance listener to be executed when consumer rebalance occurs.
listener
The consumer rebalance listener to wire in
abstract def shutdown(): Unit
