rkhachatryan opened a new pull request #15207:
URL: https://github.com/apache/flink/pull/15207
## What is the purpose of the change
```
In the new incremental mode, heap backend wraps KeyGroupsStateHandle
into IncrementalRemoteKeyedStateHandle. The latter don't compute
intersection because it is not directly aware of the offsets. So it just
returns a full keyrange if there is SOME intersection.
On recovery, unused keyGroups are filtered out by RocksDB state backend.
With this change, Heap state backend does the same.
```
