Work Description: chamikaramj commented on issue #8251: [BEAM-7029] Add
KafkaIO.Read as external transform
URL: https://github.com/apache/beam/pull/8251#issuecomment-481485803
Makes sense in general. If a IO connector offers a transform that produces
records as bytes, it makes sense to support pushing deserializers to remote
SDKs.
Looks like there's no such a read transform for Java `KafkaIO` today though.
`KafkaIO.TypedWithoutMetadata` produces a `PCollection<KV<K, V>>` while
`KafkIO.Read` produces a `PCollection<KafkaRecord<K, V>>` where a `KafkaRecord`
wraps` K`, `V` values (and other metadata) extracted from a native Kafka
record. Also, `KafkIO.Read` will not work for cross-language transforms till
we convert it to use SDF (instead of `UnboundedSource`).

> As of BEAM-6730, we can externally configure existing transforms from SDKs.
> We should add more useful transforms then just {{GenerateSequence}}.
> {{KafkaIO}} is a good candidate.
