Process large datasets efficiently by breaking them into manageable chunks to reduce memory consumption and improve performance.

| Method | Use Case | Memory Usage | Notes |

| chunk() | General processing | Moderate | May skip/duplicate if modifying filter columns | | chunkById() | Updates during iteration | Moderate | Safer for modifications | | lazy() | Large result processing | Low | Returns LazyCollection | | cursor() | Simple forward iteration | Lowest | Returns Generator |

使用 chunk()、chunkById()、lazy() 和cursor() 高效處理大型數據集，以減少內存消耗並提高性能 來源：noartem/laravel-vue-skills。
