-------------------------------
Summary: 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: 1.9.1
Reporter: Jun Qin
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.
