[PR] Flink: Deprecate 1.20 Flink support [iceberg]
talatuyarer opened a new pull request, #16517:
URL: https://github.com/apache/iceberg/pull/16517
Deprecate Flink 1.20 support in next release. This change removes all code related to Flink 1.20, as version 1.11 is now available. This ensures we focus our efforts on newer, supported Flink versions.

I think this would merit a dev list discussion, so we reach wider audience, and highlight the change to the wider community.

+1 for keeping Flink 1.20 and removing 2.0.
@stevenzwu I only had a PR for 2.1 which we merged a while ago. I believe there is one open for 2.2 from another contributor.

I agree with @pan3793 that we should keep 1.20 longer and drop 2.0 when we add the next new version.
Regarding the next version, I remember @mxm had a PR for Flink 2.2 and it was blocked due to the Iceberg 1.11.0 release to get Flink 2.1 out. Because Iceberg 1.11.0 took so long and we had Flink 2.3 released already. I am wondering if we just jump directly to add Flink 2.3 support and skip 2.2?
With that approach, we will have 1.20, 2.1, and 2.3 support.

does flink has official EOL policy? generally speaking, the LTS version (1.20) has a longer lifespan and a wider range of adoption. so I assume support for flink 2.0 should be dropped ahead of 1.20

Flink1.20 is LTS version，I recommend Iceberg long-term support adaptation; do not delete it lightly.

We usually create a single big PR where there are 4 commits:
- Rename the current top version to the new one - this helps us keep the history (2.1->2.2)
- Copy that version to the original one - this restores the current version (2.2->2.1)
- Drop the old version (1.20)
- Fix the build, so the new version compiling - we can review the required changes independently
We merge these commit without squashing them, but at the same time, so the history is clear.
This is a big change, and every other Flink PRs need to pause a bit. Since there is quite a bit of development happening, we might want to coordinate on the dev list.
