Work Description: mxm commented on issue #8251: [BEAM-7029] Add
KafkaIO.Read as external transform
URL: https://github.com/apache/beam/pull/8251#issuecomment-517490677
>Does portability allow having both external and local transforms in a
pipeline in different languages?
Yes it does. You can mix Python, Java code, and Go code in the same
pipeline. Each have their own environment via docker containers. That's also
why we are limited to standard coders to transfer data between the different
environments.
It is a bit tricky though for sources where we actually mix three different
environments a) Java via docker b) Python via docker c) native Java via the
Flink runner to run the old style unbounded sources, i.e. Kafka IO. The latter
code path will be removed once we have an adapter to run old style sources via
SplittableDoFn. If that does not make sense to you, that's alright :)
Not sure what the issue is here. Earlier I ran a semantically identical
pipeline with a ReadFromKafka and a pass-through Python transform, followed by
a WriteToKafka. Will take a closer look when I get a chance (currently
traveling).

> 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.
