-## Version Control Patterns
-
-### Change Management
-1. Batch Processing
-   ```python
-   class BatchChangeProcessor:
-       def process_changes(self, changes, chunk_size=100):
-           """Process changes in efficient batches"""
-           with transaction.atomic():
-               for chunk in chunked_queryset(changes, chunk_size):
-                   self._process_chunk(chunk)
-   ```
-
-2. Caching Strategy
-   ```python
-   class VersionCache:
-       def cache_history(self, instance):
-           """Cache version history with TTL"""
-           key = f"version_history_{instance.pk}"
-           if not cache.get(key):
-               history = instance.get_history()
-               cache.set(key, history, timeout=3600)
-   ```
-
-3. Change Tracking
-   ```python
-   class ChangeTracker:
-       def track_changes(self, instance):
-           """Track changes with metadata"""
-           return {
-               'changes': self._diff_changes(instance),
-               'metadata': self._collect_metadata(),
-               'performance': self._get_metrics()
-           }
-   ```
-
-### Performance Optimization
-
-1. Query Patterns
-   ```python
-   class HistoryQuerySet:
-       def optimized_history(self):
-           """Optimized history query"""
-           return self.select_related('branch')\
-                     .prefetch_related('changes')\
-                     .defer('large_fields')
-   ```
-
-2. Async Operations
-   ```python
-   class AsyncVersionControl:
-       async def process_large_changes(self):
-           """Handle large changes asynchronously"""
-           async with atomic():
-               # Async processing logic
-   ```
-
-3. Archiving Strategy
-   ```python
-   class HistoryArchiver:
-       def archive_old_versions(self, age_days=90):
-           """Archive old version history"""
-           threshold = timezone.now() - timedelta(days=age_days)
-           return self._move_to_archive(threshold)
-   ```
