### Caching using Redis (Summit)
#### Model Caching
```ruby
# controller
prod.get_cached_images

# product model
private

def get_cached_images
  Rails.cache.fetch(['Product', 'images', id]) do
    images.to_a
  end
end
```

- `Rails.cache.fetch` is used to initiate the cache key and look for it in the
databse
- To expire the cache, when the model updates:
```ruby
# use a callback in the model
after_commit :flush_cache

private
def flush_cache
  ExpireModelCacheJob...
  # using rake task to expi

Python 解释器会在以下情况释放 GIL：
1. **字节码计数器达到阈值**（默认每 100 条字节码）
2. I/O 操作（文件、网络、sleep 等）
3. 某些内置函数调用
4. 显式的 GIL 释放（如 C 扩展）

线程切换并不以方法为边界，方法中间也可能被切换。所以 GIL 并不能保证线程安全，需要以操作是否是原子来判断是否安全。

```python 
# 原子操作：
x = 123                    # 简单赋值
x = y                      # 变量赋值
L.append(x)                # list.append
L1.extend(L2)             # list.extend
x = L.pop()               # list.pop
d[key] = value            # dict 赋值

# 非原子操作：
x += 1                     # 需要锁
x = x + 1
