-## Table Maintenance
-
-PyIceberg provides table maintenance operations through the `table.maintenance` API. This provides a clean interface for performing maintenance tasks like snapshot expiration.
-
-### Snapshot Expiration
-
-Expire old snapshots to clean up table metadata and reduce storage costs:
-
-```python
-# Basic usage - expire a specific snapshot by ID
-table.maintenance.expire_snapshots().by_id(12345).commit()
-
-# Context manager usage (recommended for multiple operations)
-with table.maintenance.expire_snapshots() as expire:
-    expire.by_id(12345)
-    expire.by_id(67890)
-    # Automatically commits when exiting the context
-
-# Method chaining
-table.maintenance.expire_snapshots().by_id(12345).commit()
-```
-
-#### Real-world Example
-
-```python
-def cleanup_old_snapshots(table_name: str, snapshot_ids: list[int]):
-    """Remove specific snapshots from a table."""
-    catalog = load_catalog("production")
-    table = catalog.load_table(table_name)
-
-    # Use context manager for safe transaction handling
-    with table.maintenance.expire_snapshots() as expire:
-        for snapshot_id in snapshot_ids:
-            expire.by_id(snapshot_id)
-
-    print(f"Expired {len(snapshot_ids)} snapshots from {table_name}")
-
-# Usage
-cleanup_old_snapshots("analytics.user_events", [12345, 67890, 11111])
-```
-
-#### Transaction Semantics
-
-The maintenance API leverages Iceberg's transaction system:
-
-- **Context Manager**: Automatically commits changes when exiting the `with` block
-- **Manual Commit**: Call `.commit()` explicitly to apply changes
-- **Rollback**: If an error occurs in a context manager, changes are automatically rolled back
-- **Atomic Operations**: All operations within a single transaction are applied atomically
