Re: [DISCUSS] Drop older versions of Kafka Connectors (0.9, 0.10) for Flink 1.10

Hi, I’m also in favour of at least dropping support for Kafka 0.8. More generally, I think we have to be careful when recommending to use Flink connectors from older versions with a newer Flink versions. The interfaces might be stable but they might use internal code that is not stable, as show

I think this is very hypothetical, requiring a major version bump to drop an old connector version. What is the actual problem that would arise for users? We have not required a major version to drop some old connectors that in the past, and if we want to continue "mono repo" style in Flink, I don

Hi all! We still maintain connectors for Kafka 0.8 and 0.9 in Flink. I would suggest to drop those with Flink 1.10 and start supporting only Kafka 0.10 onwards. Are there any concerns about this, or still a significant number of users of these versions? Best, Stephan
