Hi Gunnar, I checked the Debezium releases overview sheet [1], and it seems the latest Debezium 3.x requires at least Java 17. As the next CDC version is expected to be based on Flink 2.x that still supports Java 11 [2], is it reasonable to keep the same JDK requirement?
The highest version that still supports Java 11 is Debezium 2.7, and it could be progressively upgraded to 3.x until we dropped Java 11 support eventually. WDYT?

I'd very much recommend going to the current 3.x, it has so many new features and bug fixes compared to 1.9.x.

If it involves debezium version updates and Flink cross version updates, would it be better to use Flink-cdc-4.0 version number? By the way, to which version will debezium be updated Xiqian YU <[email protected]> 于2025年11月3日周一 10:01写道： +1, thanks Kunni for driving this major release!

For a long time, we have received significant feedback from community users regarding the need to upgrade Flink/Debezium version dependencies. We plan to gradually address these requests in the upcoming releases. Moreover, as the framework's capabilities continue to enhance, we will devote more effort to providing more robust connectors. In this version, we will focus on the following development tasks: 1. Upgrade the Flink dependency to version 2.2 and integrate new features from the higher Flink version. This involves adding FLIP-27 API-based implementations to the current TiDB and Vitess connectors, which are currently implemented using the SourceFunction interface. 2. Add synchronized schema evolution support to the PostgreSQL Pipeline connector and introduce a new Kafka Pipeline Source connector, which has been frequently reported by users. 3. Add support for LanceDB/Milvus pipeline connectors and explore YAML-based configuration for RAG scenarios. For developers who are interested in participating and contributing new features in this release cycle, please feel free to create a task that targets cdc-3.6.0 to trace your planning features [1]. I'm happy to volunteer as a release manager and of course open to work together with someone on this. To ensure that we can complete the above plan, we plan to complete the development of Flink CDC 3.6 in 2026-02-28.
