Raghu Angadi commented on BEAM-6063:
------------------------------------

Thanks for filing this. We might keep interface based on KV<K, V> since that is more convenient for the users.

> Currently, the default input collection for {{KafkaIO.Write}} is {{PCollection<KV<K,V>>}}. To support writing of Kafka headers or different output Kafka topics, we need to change type of input collection to {{PCollection<ProducerRecord<K,V>>}}. Also, it will make sense to use {{ProducerRecord<K,V>}} instead of {{KV<K,V>}} internally in {{KafkaIO}} to keep all meta information.
> In the same time, we need to keep compatibility for old interface based on {{KV<K,V>}} but make it deprecated and totally move to {{ProducerRecord<K,V>}} later.
