## What is the purpose of the change The aim is to implement a HeapKeyValueStateIterator which can be used to produce a unified savepoint out of a HeapKeyedStateBackend ## Verifying this change The tests are still to come, as we cannot enable the unified savepoint for HeapStateBackend because we do not have the restore procedure in place yet. ## Does this pull request potentially affect one of the following parts: - Dependencies (does it add or upgrade a dependency): (yes / **no**) - The public API, i.e., is any changed class annotated with `@Public(Evolving)`: (yes / **no**) - The serializers: (yes / **no** / don't know) - The runtime per-record code paths (performance sensitive): (yes / **no** / don't know) - Anything that affects deployment or recovery: JobManager (and its components), Checkpointing, Kubernetes/Yarn/Mesos, ZooKeeper: (**yes** / no / don't know) - The S3 file system connector: (yes / **no** / don't know) ## Documentation - Does this pull request introduce a new feature?
