sealed abstract class ProducerRecord[+K, +V] extends AnyRef
ProducerRecord represents a record which can be produced
to Kafka. At the very least, this includes a key of type K
,
a value of type V
, and to which topic the record should be
produced. The partition, timestamp, and headers can be set
by using the withPartition, withTimestamp, and
withHeaders functions, respectively.
To create a new instance, use ProducerRecord#apply.
