Re: [DISCUSS] Remove Kafka 0.10.x connector (and possibly 0.11.x)

+1 to remove these two connectors. It's a lot of baggage in comparison to the workarounds that still make it possible to use older Kafka clusters. On Fri, Aug 28, 2020 at 12:06 PM Aljoscha Krettek wrote: > Yes, that should be the process. But I'd try it in a testing environment > before doing it

Yes, that should be the process. But I'd try it in a testing environment before doing it in the production environment. Aljoscha On 27.08.20 11:42, Paul Lam wrote: Hi, I think it’s okay, given that we can either migrate to the universal connector or still use the compatible 0.10/0.11 connect

Hi, I think it’s okay, given that we can either migrate to the universal connector or still use the compatible 0.10/0.11 connector of 1.11 release as Chesnay mentioned when upgrading to 1.12. IIUC, the migration process to the universal connector would be (please correct me if I’m wrong): 1. S

@Konstantin: Yes, I'm talking about dropping those modules. We don't have any special code for supporting Kafka 0.10/0.11 in the "modern" connector, that comes from the Kafka Consumer/Producer code we're using. @Paul: The modern Kafka connector works with Kafka brokers as far back as 0.10, wou

+1 to remove both the 1.10 and 1.11 connectors. The connectors have not been actively developed for some time. They are basically just sitting around causing noise by causing test instabilities and eating CI time. It would  also allow us to really simplify the module structure of the Kafka con

Hi Aljoscha, I am assuming you're asking about dropping the flink-connector-kafka-0.10/0.11 modules, right? Or are you talking about removing support for Kafka 0.10/0.11 from the universal connector? I am in favor of removing flink-connector-kafka-0.10/0.11 in the next release. These modules woul

Hi Aljoscha, I'm lightly leaning towards keeping the 0.10 connector, for Kafka 0.10 still has a steady user base in my observation. But if we drop 0.10 connector, can we ensure the users would be able to smoothly migrate to 0.11 connector/universal connector? If I remember correctly, the univ

Hi all, this thought came up on FLINK-17260 [1] but I think it would be a good idea in general. The issue reminded us that Kafka didn't have an idempotent/fault-tolerant Producer before Kafka 0.11.0. By now we have had the "modern" Kafka connector that roughly follows new Kafka releases for a
