Review comment:
```suggestion
This extended Function SDK provides an interface to initialize and release
external resources, which is easy and efficient to use and expand. Before
starting a Function, you don't have to make various judgments in the Function
interface for those resources which only need one-time initialization. After
closing a Function, you don't need to manually close the referenced external
resources. The order of releasing external resources is controlled by the
Function itself.
