[DISCUSS] Drop Savepoint Compatibility with Flink 1.2
Hi all!
For some cleanup and simplifications, it would be helpful to drop Savepoint
compatibility with Flink version 1.2. That version was released almost
three years ago.
I would expect that no one uses that old version any more in a way that
they actively want to upgrade directly to 1.11.
Even if, there is still the way to first upgrade to another version (like
1.9) and then upgrade to 1.11 from there.
Any concerns to drop that support?
Best,
Stephan

Hey Stephan,
+1.
Reading over the linked ticket and your description here, I think it makes
a lot of sense to go ahead with this. Since it's possible to upgrade via
intermediate Flink releases as a fail-safe I don't have any concerns.

+1 for dropping Savepoint compatibility with Flink 1.2
Flink 1.2 is quite far away from the latest 1.10. Especially after the
release of Flink 1.9 and 1.10, the code and architecture have undergone
major changes.
Currently, I am updating state migration tests for Flink 1.10. I can still
see some binary snapshot files of version 1.2. If we agree on this topic,
we may be able to alleviate some of the burdens(remove those binary files)
when the migration tests would be updated later.
Best,
Vino

+1 for dropping compatibility.
I personally think that it is very important for a project to keep a good pace in developing that old legacy stuff must be dropped from time to time. As long as there is an upgrade routine (via going to another flink release) that's fine.

Betreff: [DISCUSS] Drop Savepoint Compatibility with Flink 1.2
Hi all!
For some cleanup and simplifications, it would be helpful to drop Savepoint compatibility with Flink version 1.2. That version was released almost three years ago.
I would expect that no one uses that old version any more in a way that they actively want to upgrade directly to 1.11.
Even if, there is still the way to first upgrade to another version (like 1.9) and then upgrade to 1.11 from there.
Any concerns to drop that support?
Best,
Stephan
