+## Parameters
+
+{% hint style='info' %}
+NOTE: It depends on a plugin's capabilities whether can handle a `<storage>` section or not. See each plugin's documentation in detail.
+{% endhint %}
+
+The following parameters are common to all storage plugins. Individual storage plugins may add their own parameters. See each plugin's documentation in detail.
+
+* **`persistent`** \(bool\) \(optional\): If `true`, the storage reloads its data from the data source before every read/write operation and saves it back after every write operation. This keeps the data source always up-to-date at the cost of an I/O per operation. If `false`, the operations are performed against the in-memory copy only, and saving is left to `autosave` and `save_at_shutdown`.
+  * Default: `false`
+  * Note that some plugins require additional configuration to be persistent. For example, [`local`](../storage/local.md) raises a configuration error unless the plugin `@id` or the `path` parameter is given.
+* **`autosave`** \(bool\) \(optional\): If `true`, the storage periodically saves its data in the background at the `autosave_interval` interval. This is ignored when `persistent` is `true`, because every operation already saves the data.
+  * Default: `true`
+* **`autosave_interval`** \(time\) \(optional\): The interval of the periodic save enabled by `autosave`.
+  * Default: `10`
+* **`save_at_shutdown`** \(bool\) \(optional\): If `true`, the storage saves its data when the plugin shuts down. This takes effect regardless of `persistent` and `autosave`.
+  * Default: `true`
