I'm really sorry, I found that in graphrag/general/extractor.py under
def __call__, the line change.removed_nodes.extend(nodes[1:]) causes an
AttributeError: 'set' object has no attribute 'extend'. Could you please
merge the branch e666528 again? I made some modifications.

Thanks for the review! My fault! I realize my initial testing wasn't
passed.
In graphrag/entity_resolution.py
`sub_connect_graph` is a set like` {'HELLO', 'Hi', 'How are you'}`,
Neither accessing `.nodes` nor `.nodes()` will work, **it still causes
`AttributeError: 'set' object has no attribute 'nodes'`**
In graphrag/general/extractor.py
The `list.extend() `method performs an in-place operation, directly
modifying the original list and returning ‘None’ rather than the
modified list.
Neither accessing
`sorted(set(node0_attrs[attr].extend(node1_attrs.get(attr, []))))` nor
`sorted(set(node0_attrs[attr].extend(node1_attrs[attr])))` will work,
**it still causes `TypeError: 'NoneType' object is not iterable`**
### Type of change
- [ ] Bug Fix AttributeError: graphrag/entity_resolution.py
- [ ] Bug Fix TypeError: graphrag/general/extractor.py
### Related Issue: #6653
### Environment:
Using nightly version
Elasticsearch database
### Bug Description:
When clicking the "Entity Resolution" button in KnowledgeGraph,
encountered the following errors:
graphrag/entity_resolution.py
```
list(sub_connect_graph.nodes) AttributeError
```
graphrag/general/extractor.py
```
node0_attrs[attr] = sorted(set(node0_attrs[attr].extend(node1_attrs[attr])))
TypeError: 'NoneType' object is not iterable
```
```
for attr in ["keywords", "source_id"]:
KeyError I think attribute "keywords" is in edges not nodes
```
graphrag/utils.py
```
settings.docStoreConn.delete() # Sync function called as async
```
### Changes Made:
Fixed AttributeError in entity_resolution.py by properly handling graph
nodes
Fixed TypeError and KeyError in extractor.py by separate operations
Corrected async/sync mismatch in document deletion call
### What problem does this PR solve?
Removed set_entity and set_relation to avoid accessing doc engine during
graph computation.
Introduced GraphChange to avoid writing unchanged chunks.
### Type of change
- [x] Performance Improvement
