Hi everyone, As a follow-up to earlier discussions [1] [2] to externalize the connectors from the Flink repository, I would like to propose a plan to externalize these connectors. The goal of this plan is to start with moving connectors to its own repositories without introducing regressions for connector developers.
The plan is as follows: 1. A new repository is requested for a connector. 2. The code for that connector is moved to its individual repository, including the commit history 3. Any first release made for a connector in an external connector repository starts with major version 3, so 3.0.0. The reason for that is that we want to decouple the Flink releases from a connector release. If we would start with major version 2, it could cause some confusion because people could think a Flink 2.0 has been released. This does mean that each connector needs to have a compatibility matrix generated, stating which version number of the connector is compatible with the correct Flink version. 4. The group id and artifact id for the connector will remain the same, only the version is different. 5. The connector dependencies on the Flink website are updated to point to the newly released connector artifact. 6. If a connector is moved, there is one release cycle where there will be binary releases for that connector in both Flink core and from the connector repository. This is to make Flink users who are upgrading slightly easier. We will have to make a note in the release notes that a connector has been moved and that a user should update any references from the original connector artifact (from the Flink connector) to the new connector artifact (from the external conenctor version) We propose to first try to execute this plan for the Elasticsearch connector as follows: 1. We wait until the Flink 1.15 release branch is cut 2. When that's done, the Elasticsearch code (including commit history) from Flink's 1.15 release branch will be moved to the flink-connector-elasticsearch main branch. 3. When Flink 1.15 is released, we will also release an Elasticsearch connector for the external connector repository with version 3.0.0. 4. Bugfixes or improvements will be made first pointing to the external connector repository and will be cherry-picked back to the release-1.15 branch in the Flink core repository. 5. The Elasticsearch code, test etc will be removed from the master branch in the Flink core repository and dropped with Flink 1.16 Looking forward to your thoughts on this!
