Subject Re: [DISCUSS] Drop older versions of Kafka Connectors (0.9, 0.10) for Flink 1.10
Date Sun, 15 Sep 2019 23:42:40 GMT
Thanks for bringing this up, Stephan.

I am +1 on dropping support for Kafka 0.8. It is a pretty old version and I
don't think there are many users on that version now.

However, for Kafka 0.9, I think there are still quite some users on that
version. It might be better to keep it a little longer.

Given that dropping connector support is a backwards incompatible change,
technically speaking we need to bump up the major version. I am not sure if
release 1.10 is a good version to remove the code.
Personally I prefer to mark Kafka 0.8 connector as deprecated and remove
the code base in Flink 2.x.
