- Dict \<String, DataValue>
- Tuple \<DataValue, DataValue>



## Storage Model

`dorea` based on the `Bitcask` storage model. **(Log)**

All **insert, update, delete** operations are implemented as appends.

```
key: foo | value: "bar" | timestamp: 1626470590043 # Insert Value
key: foo | value: "new" | timestamp: 1626470590043 # Update Value (append info)
key: foo | value:  none | timestamp: 1626470590043 # Remove Value (append info)
```

When a storage file reaches a maximum capacity, it is archived and a new write file is created.
