If you look at the Tool and Endpoint in the plug-in alone, it is not difficult to find that in most cases it can only complete a single round of interaction, the request returns the data, and the task ends.
|
|
|
|
If there is a need for long-term storage of data, such as the implementation of persistent memory, the plug-in needs to have persistent storage capabilities. **Persistent storage mechanism allows plugins to have the ability to store data persistently in the same Workspace** , currently through the provision of KV database to meet the storage needs , the future may be based on the actual use of the introduction of more flexible and more powerful storage endpoints .

### Storage Key
|
|
|
|
#### **Entrance**
|
|
|
|
```python
|
|
self.session.storage
|
|
```
|
|
|
|
#### Endpoints
|
|
|
|
```python
|
|
def set(self, key: str, val: bytes) -> None:
|
|
pass
|
|
```
|
|
|
|
You can notice that a bytes is passed in, so you can actually store files in it.
