Interface KafkaConsumerRecord<K,V>

public interface KafkaConsumerRecord<K,V>

Vert.x Kafka consumer record

Method Summary

Modifier and Type	Method and Description
long	checksum() Deprecated. As of Kafka 0.11.0. Because of the potential for message format conversion on the broker, the checksum returned by the broker may not match what was computed by the producer. It is therefore unsafe to depend on this checksum for end-to-end delivery guarantees. Additionally, message format v2 does not include a record-level checksum (for performance, the record checksum was replaced with a batch checksum). To maintain compatibility, a partial checksum computed from the record timestamp, serialized key size, and serialized value size is returned instead, but this should not be depended on for end-to-end reliability.

checksum

@Deprecated
long checksum()

Deprecated. As of Kafka 0.11.0. Because of the potential for message format conversion on the broker, the checksum returned by the broker may not match what was computed by the producer. It is therefore unsafe to depend on this checksum for end-to-end delivery guarantees. Additionally, message format v2 does not include a record-level checksum (for performance, the record checksum was replaced with a batch checksum). To maintain compatibility, a partial checksum computed from the record timestamp, serialized key size, and serialized value size is returned instead, but this should not be depended on for end-to-end reliability.

Returns:

the checksum (CRC32) of the record.

key

K key()

Returns:

the key (or null if no key is specified)

value

V value()

Returns:

the value

headers

List<KafkaHeader> headers()

Returns:

the list of consumer record headers

record

org.apache.kafka.clients.consumer.ConsumerRecord<K,V> record()

Returns:

the native Kafka consumer record with backed information
