Zhu Zhu commented on FLINK-14942:
---------------------------------
[~qinjunjerry] from what I know, shallow copy is not new in 1.11. It has been
there for quite a long time (at least since 1.9, see
https://ci.apache.org/projects/flink/flink-docs-release-1.9/dev/libs/state_processor_api.html#modifying-savepoints).
So I agree with [~rmetzger] that it would be better to treat it as a new
feature and add it in 1.12.
Or at least it does not need to be a blocker for 1.11.2, which is a bugfix
release.
I will remove 1.11.x from the fix versions for now. We can add it back if there
is consensus to port it back to 1.11 in further discussion.
> State Processing API: add an option to make deep copy

> Key: FLINK-14942
> URL: https://issues.apache.org/jira/browse/FLINK-14942
> Project: Flink
> Issue Type: Improvement
> Components: API / State Processor
> Affects Versions: 1.11.0
> Reporter: Jun Qin
> Assignee: Jun Qin
> Priority: Blocker
> Labels: pull-request-available, usability
> Fix For: 1.12.0, 1.11.2
>
>
> Current when a new savepoint is created based on a source savepoint, then
> there are references in the new savepoint to the source savepoint. Here is
> the [State Processing API
> doc|https://ci.apache.org/projects/flink/flink-docs-release-1.9/dev/libs/state_processor_api.html]
> says:
> bq. Note: When basing a new savepoint on existing state, the state processor
> api makes a shallow copy of the pointers to the existing operators. This
> means that both savepoints share state and one cannot be deleted without
> corrupting the other!
> This JIRA is to request an option to have a deep copy (instead of shallow
> copy) such that the new savepoint is self-contained.
